Abstract

MnZn ferrite powder particles were prepared via a sol–gel autocombustion method using nitrates as raw materials. Transmission electron micrographs revealed that the particles were uniform and decentralized with sizes of 20–30 nm. X-ray diffraction patterns showed characteristic features of Mn0.5Zn0.5Fe2O4 ferrite crystals with a nanocrystalline cubic spinel structure and crystallite size of 21.5 nm. The lattice constant determined from the Rietveld refinement was 8.475 Å. A saturated magnetic induction intensity of 39.18 emu/g and coercive force of only 18.1 Oe were measured using a quantum design physical property measurement system.
