Ni_0.60Zn_0.40Fe₂O₄ ferrite was prepared via microwave assisted combustion method and sintered at three different temperatures (1100, 1200 &1300^oC). The lattice constant and bulk density increases whereas the porosity decreases (from 12% to 8% at 1100 to 1300^oC) with increasing sintering temperature. High saturation magnetization value (72.9 emu/g) is observed for the sample sintered at 1200^oC. Room temperature Mössbauer spectroscopy provided information on the magnetic phase and amount of Fe at A and B site in the lattice. Isomer shift (δ) values show that iron is in high spin Fe⁺³ states. Quadrupole splitting (Δ) values show the cubic symmetry at A-sites, possibility of local distortion at octahedral site and increase in hyperfine field with sintering temperature.
