摘要:
Neutron depolarization (P), diffraction and magnetization measurements were carried out for a cluster glass compound La0.5Sr0.5CoO3. Below T similar to 240 K significant depolarization is observed indicating the ferromagnetic transition. The temperature dependence of P appears to be correlated with the coercive field, H-C. Difference between P in zero-field-cooled and field-cooled state is found below similar to 225 K. The various features are compared with normal ferromagnet and reentrant spin-glass.
