Li-Zn-Ti ferrite samples, with compositional formula Li0.5+iZn0.2Ti0.2VtFe2.1-2tO4, '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 spine] 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 (mu(i)), the frequency dispersion of initial permeability and the corresponding loss, tan delta(mu) have been studied. The possible mechanisms involved are discussed. (C) 2004 Elsevier B.V. All rights reserved.
