Rotational spin-glass properties of Tb sub 0. 3 Y sub 0. 7 Ag
- Illinois Univ., Chicago, IL (USA). Dept. of Physics
This cubic pseudobinary compound with antiferromagnetic order and spin-glass properties below T{sub g} (36 K) was studied by magnetization-vector measurements on a field-cooled (fc) polycrystalline sample disk rotated in various fixed fields ({rvec H}). At 4.2 K, the fc-induced anisotropy field {rvec H}{sub K} is seen to turn rigidly with the sample for all rotational magnetization follows {rvec H}{sub K} very closely, it is deduced that H{sub K} > 100 kOe. At 20 K, {rvec H}{sub K} turns rigidly but only below a threshold field, above which {rvec H}{sub K} rotates up to some critical angle relative to {rvec H}, where it remains as the sample continues to turn. Thus, {rvec H}{sub K} rotates frictionally relative to the sample. Nevertheless, it is found that its magnitude continues to exceed 100 kOe. 7 refs., 3 figs.
