Abstract

The response of an electron system to a DC measurement electric field has been investigated in the case when the system is driven out of the equilibrium by the magnetic ultra-high frequency field that leads to combined transitions. The discussed model includes contributions from Landau quantization and from microwave irradiation. Impurity centers are considered as sources of scattering. It has been shown that the perturbation of the electron system by the ultra-high frequency magnetic field leads to oscillations of the diagonal components of the conductivity tensor.
