以PZT5和(Mg0.5Zn0.5)Fe2O4为原料,合成了不同配比的铁电/铁磁复相材料.XRD和SEM研究结果表明复相材料中只含有钙钛矿结构的PZT5和尖晶石结构的(Mg0.5Zn0.5)Fe2O4,无杂相生成,这说明共烧过程中两者没有发生明显的化学反应.介电频谱表明,相对介电常数随PZT5含量的增加而增加(测试频率在30 MHz以下),介电温谱表明,居里温度随频率升高而向高温移动(其值分别为250,300,326,372 ℃).电滞回线呈现了材料的漏电流较大的特点.磁滞回线表明,这种复相材料具有亚铁磁性,饱和磁化强度随铁氧体含量的增加而增加.性能测试表明,这种由PZT5和(Mg0.5Zn0.5)Fe2O4共同组成的复相材料对外同时表现出铁电性和铁磁性.
