The 0–3 type (1-x)(0.75BiFeO₃-0.25BaTiO₃)/xBaFe₁₂O₁₉ (BFO-BTO/BaM) multiferroic composites were successfully prepared by a solid-state reaction sintering process. The coexistence of perovskite BFO-BTO phase and hexagonal BaM phase was confirmed for all BFO-BTO/BaM composites. Due to the large leakage current, the breakdown electric field decreased with increasing BaM content. Nevertheless, the ferroelectric properties of the composite ceramics have also been significantly improved, mainly as the increase of remanent polarization and the decrease of coercive field, where Pr = 19.79 μC/cm², Ec = 30 kV/cm at x = 0.075. Meanwhile, the magnetic properties of BFO-BTO phase were enhanced, and the remanent magnetization linearly increased with increasing BaM content. The single domain magnetic structure was obtained for all BFO-BTO/BaM composite ceramics, and the magnetic properties changed after electric poling, which indicated the electric field controlled magnetic properties. The electric-controlled magnetic behavior was attributed to the structural phase transition. The magnetoelectric coupling coefficient α_ME of the composite material has been improved, with a maximum value of 0.61 mV/cm.Oe. Thus, the BFO-BTO/BaM magneto-electric composite system is a promising multiferroic system in information technology and sensing fields.

采用固相反应烧结工艺成功制备了0-3型(1- x )(0.75BiFeO ₃ -0.25BaTiO ₃ )/ x BaFe ₁₂ O _{19 (BFO-BTO/BaM)多铁复合材料。}所有 BFO-BTO/BaM 复合材料均证实钙钛矿 BFO-BTO 相和六方 BaM 相共存。由于漏电流大，击穿电场随着BaM含量的增加而降低。尽管如此，复合陶瓷的铁电性能也得到了显着改善，主要表现为剩磁增加和矫顽场减小，其中在x = 0.075时Pr = 19.79 μC/cm 2 ，Ec = 30 kV ^/ cm  。同时，BFO-BTO相的磁性能增强，剩余磁化强度随着BaM含量的增加而线性增加。所有BFO-BTO/BaM复合陶瓷均获得单畴磁结构，并且电极化后磁性能发生变化，表明电场控制磁性能。电控磁行为归因于结构相变。复合材料的磁电耦合系数α _ME有所提高，最大值为0.61 mV/cm.Oe。因此，BFO-BTO/BaM磁电复合系统是信息技术和传感领域很有前途的多铁性系统。
