Abstract: Pulsed laser deposited thin films of Mg0.95Mn0.05Fe2O4 ferrite were irradiated by 200 MeV Au14+ with a maximum dose up to 1 x 10(12) ions/cm(2). The as-deposited and irradiated thin films are investigated using X-ray diffraction (XRD), Raman Spectroscopy, Field emission electron microscopy (FESEM) and de magnetization measurements. XRD and Raman spectroscopy measurements; reflect the cubic spinel structure of films before and after irradiation. FESEM measurements demonstrate that films are composed of nano rods and nanocrystalline grains. Magnetic hysteresis loop measurements reveal that all the films have ferrimagnetic ordering at room temperature with enhancement in the coercive field and remnant magnetization due to irradiation.
