A giant magnetoelectric voltage coupling coefficient without direct current magnetic field observed in NiFeO-BaTiO particulate composite is reported. The particulate composite was obtained by combining hydrothermal and sol-gel method, and was studied for their crystallographic structure, morphology, magnetic, dielectric and magnetoelectric properties. Results of Mössbauer spectra demonstrated the presence of interface phase in particulate composite, where the changes of the magnetic properties in composite compared to the pure NiFeO also confirmed this. The particulate composite exhibits remarkable magnetoelectric effect through both static measurement and dynamic measurement. The special magnetoelectric property of the particulate composite is beneficial for applications in high frequency devices.
报道了在NiFeO-BaTiO颗粒复合材料中观察到的无直流磁场的巨磁电电压耦合系数。该颗粒复合材料通过水热法和溶胶-凝胶法相结合制备，并对其晶体结构、形貌、磁、介电和磁电性能进行了研究。穆斯堡尔谱结果表明颗粒复合材料中存在界面相，复合材料中磁性与纯NiFeO相比的变化也证实了这一点。通过静态测量和动态测量，该颗粒复合材料均表现出显著的磁电效应。颗粒复合材料的特殊磁电性能有利于高频器件的应用。
