Comparative Study of the Microwave and Conventionally Sintered Substituted Ni Zn Ferrites

Abstract

Ferrites have been an indispensable class of magnetic materials widely newlineused in various technological applications ranging from microwave to radio newlinefrequencies, because of their attractive electrical and magnetic properties like high newlineresistivity, low eddy current loss, square hysteresis loop etc. Recently, research on newlinespinel nano ferrites has generated enormous interest in the scientific community newlinebecause of their enhanced properties and suitability in a wide range of newlineapplications such as information storage systems, magnetic cores, microwave newlineabsorbers, medical diagnostics, radio frequency circuits, high quality filters, rod newlineantennas, transformer cores, magnetic resonance imaging and drug-delivery newlinetechnology. Efforts have been in progress to modify and tune the properties of newlinenano ferrites to suit the desirable properties for specific applications. This has newlinebeen made possible because their properties can be optimized by controlling newlinevarious factors like chemical composition, nature and amount of dopant, method newlineof preparation, sintering technique and temperature etc newline
