Effect of composition on the FMR properties of Ni x Zn 1 – x Fe 2 O 4

Nickel zinc ferrites with different contents of nickel and zinc are synthesized via pyrochemical urea nitrate processing. The microstructure of the ferrites is studied by means of XRF and SEM. Radar absorbing properties of the ferrites are analyzed via FMR. The dependence of specific radar absorption on the composition of nickel zinc ferrites and temperature is revealed.
