  • Temperature dependence of Landau coefficients in Lu(Co1-xGax)(2)

    JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS   272   505 - 506   2004.5

    　More details

    Language：English   Publisher：ELSEVIER SCIENCE BV  

    High-field magnetization was measured for typical itinerant-electron metamagnets Lu(Co1-xGax)(2) with x = 0.06 and 0.07 at temperatures from 4.2 to 300 K in pulsed magnetic fields up to 45 T. Landau coefficients A(T), B(T) and C(T) were determined by fitting measured M-H curves to the equation, H = A(T)M + B(T)M-3 + C(T)M-5. The temperature dependence of the Landau coefficients was well explained by the theory of the metamagnetic transition considering the magnetovolume effect. (C) 2003 Elsevier B.V.

  • Itinerant-electron metarnagnetism in Y(Co1-xNix)(5)

    F Ishikawa, Yamamoto, I, Umehara, I, M Yamaguchi, MI Bartashevich, H Mitamura, T Goto, H Yamada

    Language：English   Publisher：ELSEVIER SCIENCE BV  

    The magnetization processes of the Y(Co1-xNix)(5) system were measured at 4.2 K in pulsed high magnetic fields up to 40 T. The spontaneous magnetization decreases linearly with increasing Ni concentration up to x = 0.4. In the narrow concentration region 0.5less than or equal toxless than or equal to0.6, the magnetization rapidly decreases, but weak ferromagnetism persists up to x = 0.8. On the other hand, the high-field susceptibility exhibits a maximum at x = 0.55. These results show that the magnetic state of Y(Co1-xNix)(5) changes from the high- to the low-moment state at the critical concentration x = 0.55. In the vicinity of this concentration, the magnetization was measured at high pressures up to 1 GPa. The compound Y(CO0.5Ni0.5)(5) shows a very large pressure effect, indicating that it is very close to the critical concentration. (C) 2003 Elsevier Science B.V. All rights reserved.
