Abstract
Nanoparticles of Mn0.7Zn0.3Fe2O4 were synthesized using normal combustion method. Nanoparticles were characterized using conventional tools like X-Ray Diffraction (XRD) for structural confirmation. Sample was irradiated with gamma radiation (200 Gy). Particle size was estimated from XRD data for both as prepared as well as irradiated sample. Mössbauer investigations were carried out at room temperature and the spectra were fitted with a doublet attributed to superparamagnetic nature and six magnetic sextets. The broader sextet is due to tetrahedral A–site and the other four are due to octahedral B–site. Isomer shift values are consistent with Fe3+ high spin state for all sites for both as prepared as well as for irradiated sample.
