Abstract:

We report the temperature and magnetic field dependence of resistivity, Hall effect, and thermopower of an La0.85Ba0.15MnO3 single crystal. It is found that the Fermi level lies in the energy gap and conduction is by hopping. In the ferromagnetic state the variable range hopping prevails, while in the paramagnetic state hopping between nearest neighbours dominates. The small value of the activation energy of thermopower is explained by a weak asymmetry of density of states near the Fermi energy.
