Abstract

# ,Zhongyuan zhong Rd. Zhengzhou,450007 Abstract: Mn-Zn ferrite precursor powder was prepared by co-precipitation method. The Mn-Zn ferrite was obtained by sintering after being pressed. XRD and magnetic properties of the Mn-Zn ferrite were analyzed. The results show that it is in a single phase of Mn-Zn ferrite spinel after sintering. The Mn-Zn Ferrite pos- sessed high magnetic susceptibility, the standard hysteresis loop. The magnetic susceptibility and curie tem- perature of ferrite increased gradually with the zinc volume reducing and the iron content increasing.
