摘要: 用溶胶–凝胶法制备了Ba掺杂BiFeO3 (Bi0.9Ba0.1FeO3)陶瓷样品，对样品进行了结构表征与性能测试。X射线衍射和Raman光谱测试表明，Bi0.9Ba0.1FeO3陶瓷样品具有纯相结构。磁滞回线和电滞回线测试结果证明了Bi0.9Ba0.1FeO3具有良好的铁磁性和铁电性。其磁性增强源于Ba掺杂破坏了BiFeO3晶格原有的空间反演对称结构。通过外加不同电场测试样品的磁滞回线，发现电场会通过改变Bi0.9Ba0.1FeO3晶格畸变程度，从而调制铁电畴极性，铁电畴的转动会带动易磁化轴方向发生转动，从而引起磁性变化。证明了电场可以通过调控Bi0.9Ba0.1FeO3的电极化强度而改变磁特性，为进一步磁电性能调控及多态存储的应用提供了实验基础。
Abstract: The mutiferroic Bi0.9Ba0.1FeO3 ceramic sample has been prepared by the solgel method. The structure and physics properties of the sample were characterized. XRD and Raman measurements show that Bi0.9Ba0.1FeO3 sample with relatively pure phase is prepared. Magnetic hysteresis loop and ferroelectric hysteresis loop prove that Bi0.9Ba0.1FeO3 has good ferromagnetic and ferroelectric properties. The reason is that Ba doping destroys the original spatial inversion symmetric structure of BiFeO3 lattice and enhances ferromagnetic and ferroelectric domain polarity. By applying different electric fields to the hysteresis loops of samples, it is found that the electric field can adjust the ferroelectric domain polarity by changing the lattice distortion of Bi0.9Ba0.1FeO3, and the rotation of ferroelectric domain will drive the direction of easy magnetization axis to rotate, thus causing magnetic changes. It is proved the modulation effect of electric field on magnetization by regulating the electric polarization intensity of Bi0.9Ba0.1FeO3, which provides an experimental basis for the further regulation of magnetoelectric performance and the application of multi-state storage.
