The electrical conductivity and thermoelectric power of some lithium-titanium ferrites with small amounts of manganese and zinc have been studied as a function of temperature in the range of 300-550 K and are reported here. The conductivity variation shows two different regions with a large variation in the activation energies. The possible mechanisms with respect to ionic conduction and electron hopping are discussed with the support of thermoelectric power measurements. Lattice parameters are also calculated from x-ray diffractograms for confirming the single-phase nature of the ferrites.
