The zero-field-cooled magnetization at the magnetic field H = 300 Oe shows anomolous kinks at T A and T e (> T A ) far below the reentrant spin-glass-like transition temperature T f (above which a long-range ferrimagnetic ordering is set up). The ir…
The zero-field-cooled magnetization at the magnetic field H = 300 Oe shows anomolous kinks at T A and T e (> T A ) far below the reentrant spin-glass-like transition temperature T f (above which a long-range ferrimagnetic ordering is set up). The irreversibility between the zero-field-cooled and the field-cooled magnetizations, and the time decay of the thermoremanent magnetization (σTRM) are observed below the ferrimagnetic Curie temperature T C . The decay feature can be described by Ogielski's power law σTRM = At -a whose a exhibits peaks at T A , T B , T f and T C . The peak of α at Te can be fitted by the combination of Ising type and Ginzburg-Landau type expressions. Three stepwise changes of the spin-glass-like state below T f and the feature of the coexistence of short-range spin-glass and long-range magnetic ordering components above T f are discussed.
