Applying principal of topotactic reaction in the same crystal class, in the presence of bivalence metal ion and preventing from air oxidizing, the dust was transferred to spinal ferrite MnFe_2O_4. The magnetic properties of spinel ferrite MnFe_2O_4 were studies, but magnetic hysteresis loop were determined.
