    To investigate the origin of a phase transition at T-Q = 0.06 K simultaneously occurring with a superconducting transition in a cage compound PrRh2Zn20, we carried out ultrasonic measurements on a single-crystalline sample. The transverse modulus (C-11 - C-12)/2 is intimately coupled to the non-Kramers ground doublet Gamma(3), and elastic softening is observed at low temperatures. Below T-Q, the softening stops, suggesting the disappearance of quadrupole degrees of freedom. We clarified the negative quadrupole-quadrupole coupling constant and reentrant behavior of T-Q(H) in a magnetic field H. These results reveal that the phase transition at T-Q is antiferroquadrupolar ordering. The anisotropic magnetic field-temperature phase diagram is determined for H parallel to [100], [110], and [111]. A magnetic-field-induced phase transition is newly found at high fields in all three field directions. We also observed ultrasonic dispersion at around 50 K owing to the rattling motion of Zn atoms at the 16c site, and pointed out the strong electron-phonon coupling in PrRh2Zn20.

    The cage compound PrIr2Zn20 with the non-Kramers doublet ground state shows a phase transition at T-Q similar to 0.11 K. To investigate the origin of the phase transition, we have carried out ultrasonic measurements on single-crystalline samples. From the disappearance of electric quadrupole degrees of freedom at T-Q and the negative sign of a quadrupole-quadrupole coupling constant, we clarified that the phase transition is antiferro-quadrupolar ordering at the lowest temperature ever measured. We also found anisotropic magnetic field H dependence and the re-entrant behavior of T-Q(H) from the measurements in H parallel to the [100], [110], and [111] axes. The quadrupole Kondo effect interrupts the long-range quadrupole interaction at very low temperatures and thus lowers T-Q. We first reported the rattling motion of Zn atoms at the 16c site in the RT2Zn20 system.

    Low-temperature elastic properties of the clathrate compound Ce_3Pd_&lt;20&gt;Si_6 were investigated using ultrasonic measurements. Pronounced softening of elastic constants (C_&lt;11&gt;-C_&lt;12&gt;)/2 and C_&lt;44&gt; with decreasing temperature indicates a precursor of electric quadrupole ordering due to a Γ_8 quartet ground sate with an orbital degeneracy for 8c site of a Ce ion. A minimum of (C_&lt;11&gt;-C_&lt;12&gt;)/2 at T_C=170mK indicates a transition from paramagnetic phase I to an ordered phase III. Applied magnetic fields induce an antiferro-quadrupole (AFQ) ordered phase II with highly anisotropic character dep...

    We present tunneling and rattling motions of an off-center guest atom in cage
    referring to a clathrate crystal La_3Pd_{20}Ge_6. The elastic constant C_{44}
    of La_3Pd_{20}Ge_6 shows a Debye-type dispersion around 20 K obeying a
    relaxation time tau = tau_0exp(E/k_{B}T) with an attempt time tau_0 =
    2.0*10^{-12} sec and an activation energy E = 197 K. At low temperatures below
    3 K down to 20 mK, the C_{44} shows a softening of C_{44} =
    C_{44}^0(T-T_C^0)/(T-Theta) with T_C^0 = -337.970 mK and Theta = -338.044 mK.
    These facts are attributed to two different types of the off-center motions
    with Gamma_5 symmetry in 4a-site cage of La_3Pd_{20}Ge_6, a thermally activated
    rattling motion over the potential hill and a tunneling motion through the
    potential hill at low temperatures.

    &lt;p&gt;スピンゼーベック効果を決める因子の一つとしてスピン波の状態密度がある。これはq積分した動的磁化率$\chi&amp;quot;(E)$に比例することから、中性子非弾性散乱(INS)で求めることができる。我々はY_3_Fe_5_O_12_のスピン波の動的磁化率をJ-PARC/MLFのINS装置を用いて、吸収補正を含め絶対値で求めてきた。当日は超音波や熱流の効果についても併せて報告したい。&lt;/p&gt;

    &lt;p&gt;Y3Fe5O12(YIG)はスピンゼーベック効果などで他の磁性体に比べてその性能に優れており、このことは低エネルギーのスピン波に何らかの特徴があるものと思われる。一方でYIGは古くから知られる磁性体であり、光アイソレータとして実用化され、中性子散乱でもよく調べられているが、2009年に電気磁気効果が見つかるなどまだよくわかっていない点がある。特に低エネルギーのスピン波についてはこれまで報告がなかったので、今回、J-PARC/MLFの高分解能中性子非弾性散乱装置DNAなどを用いて、0.02meV付近から100meVまでのスピン波を測定したので、その結果について報告する。&lt;/p&gt;

    In order to elucidate mechanism of superconductivity in multi-band iron-based superconductors Ba(Fe1-xCox)2As2, we have performed ultrasonic measurements under high magnetic fields and hydrostatic pressures. The huge softening of the elastic constant C66 in Ba(Fe1-xCox)2As2 shows very small field dependence under high magnetic fields. The sample of concentration near the quantum critical point has the quadrupole-strain interaction, which is larger than the other concentrations. In addition, the C66 of this sample shows large pressure dependence. Theses results suggest that the quadrupole fluctuation, which are the origin of the huge softening of C66, also plays an important role in the mechanism of superconductivity.

    Observation of vacancies in crystalline silicon and elucidation of its electronic state are important issues in terms of basic and applied researches. There are rare vacancies in the crystalline silicon currently used in semiconductor industry, and the electronic state of the vacancy has cubic symmetry. We elucidated a mechanism for coupling electric quadrupoles of the vacancy and ultrasonic strains by measuring of pressure dependence of the softening of elastic constant and analyzing them with electric quadrupole susceptibilities. When concentration of the vacancy is above a critical concentration, the vacancy deforms from cubic to lower symmetry due to development of the quadrupole-strain coupling. This is consistent with previous and famous studies of the electron spin resonance.

    Observation of vacancy in silicon crystal and elucidation of its electronic state is a challenging issue in both solid-state physics and application technologies. We successfully observe vacancy orbital through elastic softening with decreasing temperature by using ultrasound measurements. Extended vacancy orbital leads to extremely strong quadrupole-strain interaction, which allows us to observe elastic softening at low temperatures even in dilute vacancy below 1 ppb. Especially, evaluation of vacancy concentration in a surface region of highly qualified silicon wafers is desirable for control of micro defects, that originates in vacancy, about nanometer in size. A benchmark of the achievement of surface acoustic wave with high frequency measurements will be a powerful evaluating method in rapidly advancing semiconductor industry.

    Ultrasonic investigation on the vacancy in silicon wafers currently used in semiconductor device fabrications is an important issue for both solid-state physics and technological applications. The electron orbital bounded around the vacancy exhibiting largely extended radius possesses the strong quadrupole-strain interaction. This provides us the sizable softening in the elastic constants caused by the vacancies existing in extremely small concentration of a vacancy per 10E10 Si atoms. In the present research, we have employed the surface acoustic wave (SAW) device to generate the Rayleigh wave propagating on the surface of the silicon wafer. We have observed the softening of the Rayleigh wave and its magnetic field dependence. We have found the interaction Hamiltonian for the vacancy orbital and the Rayleigh wave and analyzed the softening by the quadrupole susceptibility. We will develop the vacancy evaluation as a new semiconductor technology in near future.

    We have measured the ultrasonic attenuation coefficients of iron-based superconductors Ba(Fe1-xCox)2As2 and A-15 Superconductor V3Si with multiband structure. Ultrasonic attenuation coefficients show divergent increase with divergent softening of elastic constants toward the structural phase transition. Because this behavior indicates a critical slowing down phenomenon of quadrupole, the structural phase transition is a ferro quadrupole phase transition. On the other hand, Ultrasonic attenuation coefficient only shows divergent increase toward the superconducting transition. We performed analysis and calculation to focus the rotation induced by transverse ultrasound. We clarified that two conduction electrons form a hexadecapole to create a bound state and the critical slowing down occurs, which shows that the fluctuation of the hexadecapole increases divergently.

    We usually use a variety of piezoelectric transducers for generation and detecting of ultrasound signals in low-temperature measurements of elastic constants and ultrasonic attenuation coefficients. In this work, we tried to make high-frequency transducers developed by using processing technology. At first, basic process is involved in manufacturing inverted mesa-type crystals. The thickness of limited central area of conventional AT-cut quarts crystal is etched down to 5 μm for desired frequency over 150 MHz with fundamental mode. We successfully made devices with fundamental frequency of 260 MHz with blanks and applied to measure the elasticconstant C44 in Ce_3Pd_20Ge_6 with inverted mesa-type AT-cut quarts transducer. On the other hand, we found it is difficult to etch practically the LiNbO_3 and LiTaO_3 in thesame process with quarts crystal. The advanced technique using nano-particle fluid is nowdeveloped utilizing for inverted mesa-type tips made of LiNbO_3.

    We have performed systematic ultrasonic measurement on 3-20-6 type clathrate compounds and filled-skutterudite compounds to elucidate rattling and tunneling with cage-like nano-space. In the R_3Pd_20Ge_6 multi-structured ultrasonic dispersions in the elastic constant C_44 were observed. On the other hand, we revealed rattling does not emerge in the R_3Pd_20Si_6. These results evidences that conduction bands participate in the formation of anharmonic vibration with Γ_5-type charge fluctuation using the path of electron-phonon interaction. In addition, we found antiferro-type qoadrupole ordering of 8c site at 250 mK and successively of 4a site at 60 mK in Pr_3Pd_20Ge_6.

    The ultrasonic strains have specified symmetries and couple to the electric quadrupoles of the electronic and ionic quantum states. The ultrasonic measurements of the elastic constants and attenuation coefficients, therefore, may determine the quadrupole susceptibility. In the present projects, using low-temperature ultrasonic phase difference measurement apparatus with a highly velocity resolution, we have carried out a study of non-Kramers doublet of localized 4f-electron in rare-earth compounds, rattling of local oscillator in clathrate compounds, vacancy orbital in boron-doped silicon crystal in pursuing strongly correlated quantum phases associated with charge fluctuation.
