Magnetic susceptibility of a two phase manganite Pr0.925Na0.075MnO3

Abstract Magnetic measurements on the Pr 0.925 Na 0.075 MnO 3 polycrystalline manganite were performed with the aim to investigate the coexistence of the canted antiferromagnetic (CAF) and ferromagnetic (FM) phases proved by the neutron diffraction. The AC susceptibility χ ( H , T ) and the remanent magnetization M r ( T ) seem to be correlated with the FM to CAF transition temperature. The frequency dependence of χ ( H , T ) suggests a disorder character (spin-glass like) of this two phase system.
