The single-phase cubic spinel structure of all the samples has been confirmed from X-ray diffraction analyses. The lattice constant is found to increase linearly with the manganese content obeying Vegard¡¯s law. This increase in lattice parameter is explained in terms of the sizes of component ions. It is well known that density plays a key role in controlling the properties of polycrystalline ferrites. The X-ray and bulk densities of the Cu-Zn ferrite is significantly decreased whereas porosity increased with increasing Zn concentration, thereby giving an impression that zinc might be helping in the densification of the materials. SEM micrographs exhibit a decrease in grain size with increasing Zn content. The real part of initial permeability, ¦Ì¡ä increase with increasing Zn contents upto x = 0.5 after that it decreases with higher Zn content. %K Ferrites %K XRD %K Lattice Parameter %K Density %K Porosity %K Permeability %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=8488
