Abstract
Abstract (1− x )Pb(Zr 0.45 Ti 0.55 )O 3 -( x )SmFeO 3 (abbreviated as (1− x )PZT-( x )SF) solid solutions have been synthesized in composition range 0.10 ≤ x ≤ 0.15 by solid state reaction route. Rietveld analysis of X-ray diffraction data and the occurrence of A″ (450-550 cm −1 ) and A′ (650-850 cm −1 ) modes in the fitted Raman Spectra reveal the presence of tetragonal ( P 4 mm ) and monoclinic ( Cm ) phases in the samples. The weak ferromagnetic character observed from M-H hysteresis curves and the maximum value of remnant magnetization (M r ) is 7.75*10 −4 emu/g for x = 0.12. Magnetically induced ferroelectric behavior indicated the occurrence of magnetoelectric coupling in the samples. The remnant polarization (P r ) enhanced from 3.68 μC/cm 2 to 7.09 μC/cm 2 for x = 0.12 after applied magnetic field.
