摘　　要：采用水热合成方法制得了晶相单一的锰锌铁氧体,对样品进行了XRD、磁滞回线和温升曲线的测定.结果表明,锰锌铁氧体水热合成的理想条件为230℃下保温12h,且晶相单一的锰锌铁氧体具有较好的磁滞性能,在交变磁场中具有明显的磁热效应.MnZn ferrite was prepared by hydrothermal method, and its property was described by XRD, hysteresis loop and temperature rise curve. The results show that keeping 230°C for 12 h is the appropriate condition of MnZn ferrite hydrothermal synthesis, and MnZn ferrite has the good hysteresis property and obvious temperature rise when it is placed in alternative magnetic field.
