In this work magnetic nanoparticles (FeO, or ZnFeO, or SrFeO) and BaTiO microparticles were embedded in an epoxy resin for the synthesis of three series of hybrid magnetic polymer nanocomposites. Barium titanate content was kept constant, while magnetic phase content was varied. Fabricated specimens were structurally and morphologically characterized by employing scanning electron microscopy images and X-ray diffraction patterns. Results implied successful synthesis of the hybrid nanocomposites. The magnetic behavior of the pure magnetic nanoparticles and the fabricated nanocomposites was investigated via a Vibrating Sample Magnetometer. The magnetic performance of each type of magnetic phase (i.e., soft and hard) was induced in the nanocomposites, and magnetic performance is strengthened with the increase in magnetic phase content. Initial magnetization curves were used for the determination of mass magnetic susceptibility of all nanocomposites. Magnetic saturation and magnetic remanence have been found to follow a linear relationship with magnetic phase content, giving the opportunity to predict the system's response in advance.
在这项工作中，将磁性纳米颗粒（FeO、ZnFeO或SrFeO）和BaTiO微粒嵌入环氧树脂中，以合成三个系列的混合磁性聚合物纳米复合材料。钛酸钡含量保持恒定，而磁性相含量则有所变化。通过扫描电子显微镜图像和X射线衍射图谱对制备的样品进行结构和形态表征。结果表明成功合成了混合纳米复合材料。通过振动样品磁强计研究了纯磁性纳米颗粒和制备的纳米复合材料的磁行为。在纳米复合材料中诱导出了每种磁性相（即软磁相和硬磁相）的磁性能，并且磁性能随着磁性相含量的增加而增强。利用初始磁化曲线测定了所有纳米复合材料的质量磁化率。已发现磁饱和和剩磁与磁性相含量呈线性关系，从而有机会提前预测系统的响应。
