ABSTRACT
Magnetic properties of PbFe1/2Nb1/2O3 single crystal showed onset of glasslike behavior at 120 K, saturation of onset at 28 K, and freezing of glasslike state at 27.6 K. Zero field cooled (ZFC) and field cooled magnetization curves displayed sharp cusp in ZFC. Almeida and Toulouse line illustrated stability over 1000 Oe with unstable onset for low field. Magnetic hysteresis was observed below glasslike freezing temperature having steplike behavior and low coercive field ∼296 Oe, which may be due to chemical inhomogeneity, strong anisotropy, and weak dipole interaction.
