Özet:

 

A series of Co-Zn ferrite samples substituted by Mn were  prepared by the usual double sintering ceramic technique.  The x-ray  diffraction patterns of the samples confirmed the formation of  single-phase spinel structure, and x-ray analysis supply data that  suggests the cation distribution of the material.  The tetrahedral and  octahedral radius permits one to calculate the theoretical lattice  parameter and the bond lengths Fe-O at A and B sites.  The particle  size of the given samples was measured from the Scherer equation and a  correlation was found between particle size, and structural and  magnetic properties.  The XRF confirmed the presence of stoichiometric  solid-state reaction in the material.  The saturation magnetization  Ms decreases continuously with increase of Mn content.  For  Co0.6 Zn0.4 Mnx Fe2 - x O4 , the Neel model for the two  sub-lattice can be used up to x = 0.8 to explain the compositional  variation of magnetic moment due to the reduction of the A-B  interaction.  Above x = 0.8, the reduction of the B-B interaction is  responsible for an increase in the magnetic moment due to the canting  effect.
