Magnetic properties of the spinel structure Li0.5+0.5xTixFe2.5-1.5xO4
with x = 0 up to 0.5 have been studied. The initial permeability mu(i)
was measured as a function of temperature at a constant frequency of
10 kHz. A maximum value was observed for each composition indicating t
he Curie temperature T-C which decreases with increasing Ti concentrat
ion. The magnetization M and B-H loop were measured at RT in the range
of magnetizing field from 0 up to 1200 Am-1 and at constant field H =
205 Am-1, respectively. The relative permeability mu(r), depends on t
he magnetizing field and composition. It was found from the B-H loop t
hat the remanence induction B-r and the apparent loss energy P-s depen
d on the composition but the coercive force H-c is independent of comp
osition.
