Magnetic structure and properties of Mn-Zn ferrites prepared by radiation-enhanced thermal sintering

2500NMS2 Mn-Zn ferrites have been produced by radiation-enhanced thermal sintering. We have studied the effect of basic ferrite composition and doping on the electromagnetic properties of ferrite products after radiation-enhanced thermal sintering. The results demonstrate that doping with bismuth oxide as a low-melting-point material allows one to activate sintering processes, thereby improving the performance of the material. Mössbauer spectroscopy and X-ray diffraction have been used to investigate general aspects of phase transformations during the radiation-enhanced thermal sintering of green compacts. The addition of surfactants is shown to be effective in raising the density of green compacts and improving the performance of the ferrites.
