摘要/Abstract

摘要： 以CoFe₂O₄压磁体、掺CuO和CeO₂助烧剂的压电体Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃为基本叠层材料, 采用界面固相熔融渗透法制备了掺助烧剂Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃-CoFe₂O₄叠层复合陶瓷。叠层复合陶瓷的压电压磁相叠层界面结合良好。随着压磁相与压电相厚度比比率的增加, 叠层复合陶瓷的饱和磁致伸缩系数–λ从67×10^-6增加到134×10^-6、压电系数d₃₃从340 pC/N逐渐减小到205 pC/N; 磁电耦合系数先增大后减小, 在厚度比为2、外磁场为100 mT时得到最大值3200 mV/(cm·mT)。

Abstract: The Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃-CoFe₂O₄ laminated composite ceramics composed of the piezomagnet CoFe₂O₄, and the piezoelectrics Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃ with the sintering agents CuO and CeO₂, were prepared by the interfacial solid-state melt infiltration technique. It is found that a good interfacial bonding between the piezomagnet and piezoelectrics is obtained. With the increasing thickness ratio of piezomagnet to piezoelectrics, the magnetostriction coefficient (–λ) of the laminated ceramics increase, the piezoelectric coefficient (d₃₃) decrease, and the magnetoelectric coupling coefficient (α_E) increases firsty and then decreases. The values of –λ and d₃₃ of the laminated ceramics are in the range from 67×10-6 to 134×10^-6 and 205 pC/N to 340 pC/N, respectively. At dc magnetic field of 100 mT along with ac frequency of 230 kHz and the thickness ratio of 2, a maximum value of α_E=3200 mV/(cm·mT) is achieved for the laminated ceramics.

Key words: Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃, CoFe₂O₄, laminated ceramics, magnetoelectric coupling effects
