ABSTRACT. Mn and Zn ferrites belong to the group of soft ferrite materials characterized by high magnetic permeability, low power loses and used as electro ceramic materials in transformers, sensors, choke coils, magnetic recording heads, noise filters, information storage systems, medical diagnostic devices and biomedical devices. The Mn and Zn ferrites can be prepared by various methods such as ceramic method, co-precipitation, sol–gel, hydrothermal etc. In present work, ferrite Nano particles prepared by cost effective sol gel method. X-Ray Diffraction analysis (XRD) used to identify the phase formation of Zn and Mn ferrites and its crystal system. The particle size and elemental analysis revealed through scanning electron microscopy (SEM – EDAX) assisted with Energy Dispersive X – Ray images. Electrical properties were carried out using Keithley Measurement unit.
