Neutron depolarization and diffraction studies in cluster glass La0.5Sr0.5CoO3

Neutron depolarization ( P ), diffraction and magnetization measurements were carried out for a cluster glass compound La 0.5 Sr 0.5 CoO 3 . Below T ∼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 ∼225 K. The various features are compared with normal ferromagnet and reentrant spin-glass.
