中文摘要 | The structure and magnetic properties of arc-melted Dy2Co17-xGax compounds were studied. These compounds have the hexagonal Th2Ni17-type structure for 0 less than or equal to x less than or equal to 3 and the rhombohedral Th2Zn17-type structure for 3 less than or equal to x less than or equal to 6. The unit cell volume shows an approximately linear increase at a rate of about 7.7 Angstrom(3) per Ga atom. The Curie temperature was found to decrease with increasing Ga concentration. The saturation magnetization decreases linearly with increasing Ga content from 7.0 mu(B), f.u.(-1) for x=0 to -7.9 mu(B), f.u.(-1) for x=6. The exchange coupling constants J(DyCo) and J(CoCo) have been derived by analyzing both the field dependence and the temperature dependence of the magnetization. An approximately constant value of J(DyCo) indicates that the substitution of Ga for Co has only a small influence on the exchange coupling between the Dy and Co atoms. The effect of Ga substitution on J(CoCo) is strong, leading to a linear decrease of T-C in the Dy2Co17-xGax compounds. (C) 1998 Elsevier Science S.A. |
