Abstract:

The two-band Hubbard model is studied using electric-field heating of the electronic and magnetic subsystems of magnetic semiconductors. The sample EuO1-delta is described using the experimentally observed significant dependence of the magnetization on the electric field and the S- or N-shaped current-voltage characteristics. It is shown that for thin films, smallest thickness may impair the stationary mode and the emergence oscillations of the current or the voltage. The length-to-thickness ratio of the film determines the period of this oscillation. (C) 2014 Elsevier B.V. All rights reserved.
