Abstract :
This study reports the temperature- and time-dependent magnetization of the ferromagnetic phase in epitaxial FeRh thin films across the antiferromagnetic-ferromagnetic transition on both heating and cooling process by vibrating sample magnetometry. The thin films are deposited on MgO (001) substrates by co-evaporation method and vacuum annealed at 700 K for 2 h. X-ray diffraction is employed for structural characterization. Results from the magnetization curves indicate that the nucleation and growth behaviors of the single crystalline thin film are similar to crystallization of solids.
