Abstract

The electrical resistivity of the ferrites Mg1+tFe2-2tTi t O4 (t=0.1, 0.3, 0.4, 0.5) has been measured in the temperature range of 30 to 300° C. A break in Inϱ against 1/T aroundTC has been observed. This break is associated with a change in the activation energy around the Curie temperature. The conductivity behaviour is discussed in terms of the cation distribution in these ferrites.
