Beschreibungen/Notizen

• Magnetization-vector measurements were performed on a field-cooled Cu86Mn14 sample disk rotated in a stationary field H. Our results at 4.2 K reveal that the induced anisotropy field HK, which rotates rigidly with the sample for all H, is predominantly unidirectional but with higher-order components that are not negligible. HK continues to rotate fairly rigidly up to some threshold temperature, above which at sufficiently high H it turns irreversibly relative to the sample towards the direction of H. The threshold temperature (‖10 K) is well below the spin-glass freezing point (‖70 K). Comparisons are made with similar results previously obtained for field-cooled Ni75Mn25.
