Abstract :
The variations in saturation magnetization, Curie temperatures, magnetocrystalline anisotropy. initial permeability, and magnetic losses of Ni ferrites substituted with Sn4+ and Zn2+ ions are studied. An additional aim is to find the zone of utility from the frequency spectra of initial permeability and variation of temperature coefficient and percentage of disaccommodation from the point of view of stability of these ferrites. A comparison of these magnetic parameters is made as a function of increasing tin as well as zinc concentrations
