采用常规陶瓷制备工艺制备了xLaySr(1-y)MnO3+(1-x)[0.2PbZn0.5Nb0.5O3-0.8Pb0.33Zr0.67TiO3](x=0.025、0.05、0.075、0.1、0.15、0.2,y=0.7、0.9)三元体系陶瓷,系统研究了不同成分LSMO掺杂对PZN-PZT磁学及电学性能影响。结果表明,掺入不同比例的LSMO均溶解入PZN-PZT晶格,导致PZN-PZT峰位偏移;随着LSMO掺杂量的提高,陶瓷的矫顽场E及剩余极化强度Pr降低;原本分别呈现铁磁性和反铁磁性的LyS(1-y)MO3(y=0.7、0.9)磁性消失;随着LMSO掺杂量的提高,晶粒尺寸变大。
Ternary system ceramic Pb(Zn,Nb) O3-(Pb(Zn,Ti) O3) 1-x(LaySr1-yMnO3) x prepared by solid state reaction were investigated.The results indicated that LSMO had all soluted into PZN-PZT lattice,remanent polarization and coercive field decreased as x increasing;magnetism disappeared when LSMO was dissolved into PZN-ZPT lattice,ceramic grain size decreased as x increasing.
