Structural and Physical Properties of Cu0.12Mn0.88Fe2O4 Prepared by Combustion Technique

The nanocrrystalline Cu0.12Mn0.88Fe2O4 ferrite have been successfully synthesized by combustion technique. The observed particle size of Cu0.12Mn0.88Fe2O4 is found to be 9 nm. Disc- and toroid-shaped samples are prepared and sintered at various temperatures (1150, 1200, 1250, 1300 and 1350�C) in air for 1 hour. Structural and surface morphology are studied by X- ray diffraction (XRD) and high resolution optical microscope, respectively. The initial permeability of this composition is characterized by high frequency (10 kHz-120MHz) complex permeability measurements. The influence of microstructure and sintering temperatures on the initial permeability of Cu0.12Mn0.88Fe2O4 ferrite will be discussed in this paper.
