摘要：

Electrical conductivity and thermoelectric power measurements on single crystalline titanomagnetites are reported for the temperature range of 80 up to 1100 K. The results can be well explained in terms of hopping conduction in disordered systems; the conduction is governed by electron-electron and electron-titanium interactions, leading to a randomization of the site-energies. Both interaction parameters are in the order of 0.1 eV. From the experimental results a tentative energy level scheme has been deduced for the complete mixed series Fe-3-xTixO4.
