Article Preview

Abstract:

Multiferroic ceramics of Bi5Ti3Fe1-xNixO15(x=0.1,0.2,0.5,0.7) are synthesized b the conventional solid state reaction, and their microstructure, magnetic properties are investigated. X-ray diffraction patterns show that a four-layer Aurivillus phase is formed in each sample and the diffraction peaks change obviously with the temperature increasing. The Ni ion modification induces remarkable ferromagnetism (FM) at room temperature. And the x=0.2 sample has the greatest saturation magnetization Ms~0.26552 emμ/g, and the coercive field Hc~ 0.65478 kOe
