The invention relates to a multiferroic material and a preparation method thereof. The preparation method comprises the following steps: preparing a ferromagnetic substance, preparing a ferroelectricsubstance, mixing the ferromagnetic substance and the ferroelectric substance according to a mixing ratio of 2: 1, adding an accelerant and a main material, stirring at normal temperature for a certain time to obtain a soft molded body, adding a hardener to the soft molded body and mixing, after mixing, putting the mixture into a cavity heated by a far infrared lamp, heating for a specific periodof time when the internal temperature of the cavity reaches 70-80 DEG C and the internal temperature of the soft forming body reaches 100-120 DEG C, heating to the temperature, hardening to form a hard molded body, and storing at 5 DEG C to obtain the multiferroic material. According to the scheme, the ferromagnetic substance with the magnetic property and the ferroelectric substance with the electric property are combined, the preparation process does not need a specific heat treatment and slow cooling process, the cost is low, and the obtained multiferroic material can be widely applied.
本发明涉及一种多铁性材料及其制备方法，在制备时采用以下方式：制备铁磁性物质；制备铁电性物质；将铁磁性物质与铁电性物质以2:1的混合比例混合，并加入促进剂及主材，在常温下搅拌一定时间得到软质成形体；向软质成形体中添加硬化剂并进行混合；混合后投入到通过远红外线灯进行加热的腔体内部；并在腔体内部温度达到70‑80℃且所述软质成形体内部温度达到100至120℃的状态下进行加热特定时间；加热到上述温度发生硬化形成硬质成形体，并在5℃下进行保管，得到多铁性材料。本方案通过对具有磁特性的铁磁性物质与具有电特性的铁电性物质进行结合，制备工艺不需要特定的热处理及缓冷过程，成本低，得到的多铁性材料能够被广泛应用。
