Abstract
Electrical conductivity of manganese-substituted lithium ferrites was inves tigated from room temperature to well beyond the Curie temperature. The ele ctrical conduction in these ferrites is explained on the basis of the hoppi ng mechanism. Plots of log(sigmaT) vs. 10(3)/T show a transition near the C urie temperature. The carrier concentration mobility of charge carriers has been discussed as a function of composition. (C) 2001 Elsevier Science B.V . All rights reserved.
