EXPERIMENTAL TECHNIQUES TO STUDY PHYSICAL, ELECTRIC, DIELECTRIC AND MAGNETIC PROPERTIES OF FERRITES: A SURVEY

Abstract: Various experimental techniques are used to study different properties of ferrites. Using X-ray diffraction, physical and structural properties like lattice constant, X-ray density, porosity, particle size, theoretical lattice constant and cation distribution are determined. IR study is useful to determine position of different vibration modes, bond lengths and force constant. Under electric and dielectric study, dc resistivity, ac resistivity, dielectric constant, dielectric loss and dielectric loss tangent are determined. Magnetic properties are measured using pulse field magnetic hysteresis loop tracer. Under this study magnetic properties like saturation magnetization, coercivity, remanence magnetization etc are measured. Present paper reports use of these experimental techniques to study various properties of ferrites.

Keywords: Lattice constant, porosity, dielectric constant, hysteresis, magnetization.
