Nanocrystalline MgxNi0.2Cu0.8-xFe2O4 (x = 0.5 & 0.6) ferrite material has been synthesized by sol-gel method for different compositions. The prepared materials were sintered at 400 0C for four hours, after that it was characterized by XRD, SEM, VSM and IR before laser irradiation. Then the prepared samples was irradiated by He-Ne laser of power 35mW with different time and after it was characterized to study the different properties of the samples by using X-Ray Diffraction (XRD). The Infrared Spectroscopy (IR) confirmed that the synthesized material is ferrite. The ferrite material may be plays vital role in biomedical sensor. The SEM shows surface morphology of the ferrite material. He-Ne laser irradiation on nanocrystalline ferrite materials shows remarkable changes like particle size decrease after irradiation of laser and coercivity of the sample changes. The lattices plane and bond length of the sample also calculated from XRD.
