Ferrite nanoparticles of two different systems, namely Ni0.65Zn0.375In0.25Ti0.025Fe1.70O4 and Mn0.75Zn0.18Fe2.07O4, have been prepared by two different methods of ball milling (mechano synthesis) and coprecipitation (soft chemistry) respectively to investigate the effect of swift heavy ion irradiations on the structural, magnetic and ferromagnetic resonance parameters on these systems. The powder samples of Ni–Zn and Mn–Zn ferrites were irradiated with 190 MeV Ag15+ ion with fluences of 1 × 1013 ions/cm2 and 5 × 1012 ions/cm2 respectively using the 15 UD Pelletron Accelerator at NSC. The unirradiated and irradiated samples were then subjected to characterization techniques such as X-ray diffraction, vibrating sample magnetometer and ferromagnetic resonance spectrometer. The results of these characterizations are found to be different for irradiated from that of the pristine sample. The modifications in respect of irradiated samples are explained in terms of the ion-induced disorder.
