Some magnetic properties of the spinel structure compound, Li0.5+0.5xTi x Fe2.5-1.5xO4, wherex=0−0.5, have been studied by different methods. The initial permeability, μi, was measured as a function of temperature at a constant frequency of 10 kHz. A maximum value was observed for each composition indicating the Curie temperature,T c , which decreases with increasing titanium concentration. The magnetization,M, and theB-H loop were measured atRT in the range of magnetizing field from 0–1200 Am−1 and at constant fieldH=205 Am−1, respectively. The relative permeability, μr, depends on the magnetizing field and composition. It was found from theB-H loop that the remanence induction,Br, and the apparent loss energy,Ps, depend on the composition but the coercive force,Hc, is independent of composition.
