Description
The magnetic behaviour of La0.5Sr0.5CoO3 at low magnetic fields has been studied by ac susceptibility, and field cooled (FC) and zero field cooled (ZFC) magnetization measurements. The cluster-glass-like magnetic behaviour of the compound is found to originate from its magnetocrystalline anisotropy as similar properties are observed for ferromagnetic systems also. The cluster glass freezing temperature and its magnetic field dependence, the irreversibility between the FC and ZFC magnetization curves, the shape of the low-field susceptibility curves, etc are related to the magnitude and temperature variation of the coercivity (HC) which is a measure of the anisotropy, and the ratio HA/HC where HA is the applied magnetic field.
