De Haas-van alphen effect and magnetization in dodecaborides HoB12, ErB12 and TmB12

V. Pluzhnikov, N. Shitsevalova, A. Dukhnenko, A. Czopnik, V. Nizhankovskii, R. Settai, Y. Onuki

JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS 320 ( 9 ) 1597 - 1604 2008年5月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

High-quality HoB12, ErB12 and TmB12 single crystals with the fcc UB12 structure are grown; field dependencies of their magnetization are measured up to 14 T; angular dependences of the magnetization in the ( 1 0 0) and ( 1 1 0) planes are calculated, and properties of their Fermi surfaces (FS) are studied using the de Haas-van Alphen (dHvA) effect. The angular dependences of the dHvA frequencies in the ( 1 0 0) and ( 1 1 0) planes are obtained and values of their effective cyclotron masses are determined. The oscillation frequencies lie in the range (11.7-127.3) x 10(2) T, and cyclotron masses within the range (0.4-1.45) m(0). For ErB12 and TmB12, we found branches in the oscillation spectrum that originated from FS fragments with spins along and opposed to the. eld, and the energy of the exchange interaction is estimated. Its value for the gamma-branch in ErB12 is equal to 8.2 meV, and for the gamma-, beta- and theta-branches in TmB12; these values are 14.5, 28.5, and 18.3 meV, respectively.

De Haas-van Alphen effect in CeTl3 under pressure

R. Settai, T. Endo, T. Fujie, Y. Onuki, D. Aoki, I. Sheikin

PHYSICA B-CONDENSED MATTER 403 ( 5-9 ) 766 - 768 2008年4月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

We report the pressure dependence of electrical resistivity and de Haas-van Alphen effect in an antiferromagnet CeTl3. With increasing pressure the Neel temperature T-N decreases monotonically and both rho(0) and A values of the resistivity rho = rho(0) + AT(2) in the Fermi liquid relation increase, reflecting the approach to the quantum critical point. The critical pressure P-c is estimated to be about 6 GPa. The cyclotron effective masses also increase with increasing pressure. (C) 2008 Published by Elsevier B.V.

Magnetism and crystalline electric field in RRhIn5 (R : rare earth)

PHYSICA B-CONDENSED MATTER 403 ( 5-9 ) 1023 - 1025 2008年4月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

We studied systematically a series of the ternary compounds RRhIn5 (R: rare earth) which were grown in the single crystalline form by means of the flux method. Most of these compounds order antiferromagnetically at low temperatures, except for R = Y, La, Pr and Yb. The observed temperature dependence of the specific heat and the anisotropic features in the magnetic susceptibility and magnetization have been analyzed on the basis of the crystalline electric field (CEF) model, and an interesting relationship between the anisotropic exchange interaction and the CEF effect is obtained for RRhIn5 compounds.

Intimate interplay between superconductivity and antiferromagnetism in CeNiGe3 : A(73) Ge-NQR study under pressure

A. Harada, H. Mukuda, Y. Kitaoka, A. Thamizhavel, Y. Okuda, R. Settai, Y. Onuki, K. M. Itoh, E. E. Haller, H. Harima

PHYSICA B-CONDENSED MATTER 403 ( 5-9 ) 1020 - 1022 2008年4月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

We report the Ge-73-NQR studies on the antiferromagnetic (AFM) heavy-fermion compound CeNiGe3 which shows two domes like pressure-induced superconducting phases in the pressure (P) ranges of 1.7-3.7GPa and 5.9-7.3GPa denoted as SC1 and SC2, respectively [M. Nakashima, et al., J. Phys. Condens. Matter. 16 (2004) L255, H. Kotegawa, et al., J. Phys. Soc. Jpn. 75 (2006) 044713]. The NQR spectra have revealed a change from an incommensurate AFM structure at P = 0 and 2.0 GPa into a commensurate one at P = 2.8 GPa. The onset of the SCI may be relevant to an intimate evolution from the incommensurate into commensurate AFM-spin structure as P increases. (c) 2007 Elsevier B.V. All rights reserved.

AC heat capacity and resistivity measurements on the pressure-induced superconductor CeIrSi3 without inversion center

N. Tateiwa, Y. Haga, S. Ikeda, T. D. Matsuda, E. Yamamoto, Y. Okuda, Y. Miyauchi, R. Settai, Y. Onuki

PHYSICA B-CONDENSED MATTER 403 ( 5-9 ) 1156 - 1158 2008年4月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

We present the result of an antiferromagnet CeIrSi3 without inversion center by measuring the heat capacity and the electrical resistivity of CeIrSi3. Both physical quantities were measured in the same run for the same single crystal sample. A huge heat capacity anomaly was observed at the superconducting transition temperature T-sc = 1.6 K where the zero-resistivity was observed. The jump of the heat capacity Delta C-ac/C-ac is 5.7 +/- 0.1 at 2.58 GPa. This value is the largest among previously reported superconducting materials, indicating the strong coupling superconductivity. The electronic specific heat coefficient just above T-sc is roughly estimated to be 100 +/- 20 mJ/K-2 mol at 2.58 GPa, which is the same as gamma 120 +/- 20 mJ/K-2 mol at ambient pressure.
