摘要
分析了单相材料性能及混合比对复合材料磁电效应的影响，探讨了混合烧结磁电复合材料的相分布。选取ｋ３３大的ＰＺＴ（Ｂ）为压电相、Ｎｉ（Ｃｏ，Ｍｎ）Ｆｅ２Ｏ４为磁致伸缩相，采用混合烧结法，获得了磁电转换系数（ｄＥ／ｄＨ）ｍａｘ达０．３１４２Ｖ／Ａ的磁电复合材料。
This paper reports the affects of the single phase material properties and the mixed ratios on magnetoelectric effects of the composite, and the discussing result of the phase distribution of the sintered magntoelectric composite. By selecting the PZT (B) with large k33 as piezoelectric phase and Ni (Co, Mn) Fe2O4 as magnetostriction phase, together with sintering method, we obtained the magnetoelectric composite material with the maximum value of the conversion factor (dE/dH)max up to 0. 3142V/A.
