摘　　要：以锆钛酸铅(PZT)为压电相,分别以Ni和非晶铁合金(Metal-glass)为磁致伸缩相,采用焊接的方法制备了层状磁电复合材料Ni/PZT/Ni和Metal-glass/PZT/Metal-glass,并研究其在0~100℃范围内的磁电效应.结果表明,通过焊接复合得到的2种层状磁电复合材料都表现出良好的温度稳定性,在0~100℃范围内磁电电压系数基本保持恒定,有望用于高温磁电器件的设计.Using lead zirconate titanate(PZT)as piezoelectric phase,and Ni and amorphous ferroalloy(Metal-glass)as magneto-strictive phase,two kinds of laminated magnetoelectric composites,Ni/PZT/Ni and Metal-glass/PZT/Metal-glass,were prepared by welding method.The magnetoelectric effects of all laminated magnetoelectric composites were measured at temperature ranging from 0℃to 100℃.The results showed that both laminated magnetoelectric composites bonded by welding exhibited very good thermal stability,and their magnetoelectric voltage coefficient remains constant at 0-100℃,which made them suitable for high temperature applications.
