Hysteresis and initial permeability behavior of vanadium-substituted lithium-zinc-titanium ferrite

Li-Zn-Ti ferrite samples, with compositional formula Li0.5+tZn0.2Ti0.2VtFe2.1-2tO4, 't' ranging from 0.0 to 0.25 in steps of 0.05 were prepared by the ceramic route. XRD results confirmed the single-phase spinel structure of the samples. SEM photomicrographs have revealed the grain size of the samples. B-H loops have been traced for all the samples and the various hysteresis parameters like coercivity, remanence and remanence ratio have been studied as a function of composition. Compositional dependence of initial permeability (μi), the frequency dispersion of initial permeability and the corresponding loss, tan δμ have been studied. The possible mechanisms involved are discussed
