Abstract

The La_1.5Ba_0.5Co(Mn_0.5Ti_0.5)O₆ (0.5LBCMT) ceramics comprising multi-valence ions was synthesized by solid-state reaction route for the first time. X-ray diffraction analysis confirmed the monoclinic phase with space group

P 2_{1} / n

. Field emission scanning electron micrographs (FE-SEM) showed average grain size of 0.56

μ m

. Raman spectra result was compatible with the structural analysis of the sample. Magnetization hysteresis at 5 K and moderate Curie temperature (125 K) was observed. Polarization-electric field (P-E) hysteresis measurement confirmed the reduced ferroelectric nature. The results demonstrated that 0.5LBCMT sample caused magnetic ordering and a switchable ferroelectric state.

新型多价离子La1.5Ba0.5Co(Mn0.5Ti0.5)O6钙钛矿的结构、磁性和铁电性能

采用固相反应方法首次合成了La1.5Ba0.5Co(Mn0.5Ti0.5)O6 （0.5LBCMT）多价离子陶瓷。x射线衍射分析证实其为单斜相，空间群为P21/n。场发射扫描电镜（FE-SEM）显示，样品的平均晶粒尺寸为0.56 μm。拉曼光谱结果与样品的结构分析结果一致。在5 K和中等居里温度（125 K）下观察到磁化迟滞现象。极化电场（P-E）迟滞测量证实了铁电性的降低。结果表明，0.5LBCMT样品产生了磁性有序和可切换的铁电态。
