Magnetisation measurements and ferrimagnetic resonance studies of five compositions of lithium-titanium ferrites were carried out as a function of temperature in the range 300-700 K. The magnetic moments of the samples were measured using a vibrating sample magnetometer, and from the variation with temperature the Curie temperature was determined. From ferrimagnetic resonance studies the linewidth, g-factor and resonance field were determined as a function of temperature in the range 300-600 K. The influence of non-magnetic titanium ions on the values of saturation magnetisation. Curie temperature and ferrimagnetic resonance parameters were analysed. © 1988.
