A great deal of information is found in the literature on various ferrite materials. It is well known that magnetic material had been industrialized about a century ago and has been used as a vital material for transformer cores. It deals with experimental methods of (i) synthesis of nano ferrites and (ii) their characterization techniques. Basic and working principles of characterization techniques and equipment that are used in this investigation for experimental studies in this investigation are presented in detail.XRD, TEM, Dielectric characterization of nano ferrites, dc electrical resistivity measurements, VSM the samples are characterized using X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM), Vibrational Sample Magnetometer (VSM). The specific saturation magnetization (Ms) of the samples was measured. Electrical studies on the materials under investigation are carried out by using the standard method. All the samples indicated a single spinel crystalline phase with cubic structure formation. The average particle size obtained from TEM is ranged from 24 to 90 nm.
