Nizn Ferrite Magnetic Behaviour As Inferred from Its Dielectric Data Ismail Ismayadi

This book discusses the effect of the sintering temperature, sample temperature and frequency on the magnetic and dielectric properties and microstructure of the NixZn1-xFe2O4 with composition x=0.5 and 0.3 samples prepared by the conventional processing method. Complex-plane permittivity plots have been widely employed to reveal different types of dielectric polarization in polycrystalline ceramics. In this book we present a simple-manner adaptation of that technique to reveal magnetic polarization mechanisms using complex-plane permeability plots in a nickel-zinc ferrite material. The dielectric polarization was contributed by the interfacial and dipolar polarizations. Meanwhile the magnetization process was probably dominated by magnetic domain wall movement and magnetic spin rotation.
