Abstract

In this study, Bi0.8Ba0.2FeO3 modified Na0.5Bi0.5TiO3 ceramics having composition (1 - x)(Na0.5Bi0.5TiO3) - x(Bi0.8Ba0.2FeO3) with 0 <= x <= 0.40 are fabricated by conventional solid state reaction technique. Rietveld analysis of X-ray diffraction pattern of the prepared ceramics revealed that all the samples crystallized into single phase with rhombohedral symmetry (R3c space group). Magnetic measurements were performed at room temperature up to a field of 6 kOe. The magnetic hysteresis loops for samples x <= 0.10 show linear magnetic field dependence of magnetization with narrow hysteresis loop, indicating the typical antiferromagnetic nature (AFM) with canted spins. For samples 0.20 <= x <= 0.40, an appreciable increase in the values of remnant magnetization and coercive field are observed. Thus, the addition of BBFO content gives rise to significant increase in magnetization.
