Permeability Spectra of Co Substituted Ni Ferrites

Abstract

The paper presents the test results of preparing a set of Co substituted Ni ferrites Ni 1-2 Co 2 Ft 7 O 4 (x=0.04 to 0.25) as a material which absorbs the energy of the electromagnetic ware at the X band. A new method of determining the dependence of the microwave complex permeability on the frequency is described briefly. © 1991 IEEE
