将分散的Ni0.8Zn0.2Fe2O4铁磁颗粒掺入Sr0.5Ba0.5Nb2O6弛豫铁电基体中制备了新型磁电复合材料。 Sr0.5Ba0.5Nb2O6和Ni0.8Zn0.2Fe2O4共存得到致密的复合陶瓷，它们可以电极化和磁极化，表现出显着的磁电效应。 70mol% Sr0.5Ba0.5Nb2O6 复合材料的最大磁电电压系数为 26.6mV/cm/Oe，远大于磁电化合物和固溶体。在未来磁电材料的发展中，可以方便地使用无铅(Sr,Ba)Nb2O6松弛剂作为铁磁/铁电复合材料的基体。
Novel magnetoelectric composites were prepared by incorporating the dispersed Ni0.8Zn0.2Fe2O4ferromagnetic particles into Sr0.5Ba0.5Nb2O6relaxor ferroelectric matrix. Dense composite ceramics were obtained with the co-presence of Sr0.5Ba0.5Nb2O6and Ni0.8Zn0.2Fe2O4, and they could be electrically and magnetically poled to exhibit a significant magnetoelectric effect. A maximum magnetoelectric voltage coefficient of 26.6mV/cm/Oe was observed from the composites with 70mol% Sr0.5Ba0.5Nb2O6, which was much greater than that of magnetoelectric compounds and solid solutions. It is convenient to use the Pb-free (Sr,Ba)Nb2O6relaxor as the matrix for ferromagnetic/ferroelectric composites in the future development of magnetoelectric materials.
