Electronic transport through a two-level system driven by external electricfield and coupled to (magnetic or non-magnetic) electron reservoirs isconsidered theoretically. The basic transport characteristics such as currentand tunnel magnetoresistance (TMR) are calculated in the weak couplingapproximation by the use of rate equation connected with Green functionformalism and slave-boson approach. The time dependent phenomenon is consideredin the gradient expansion approximation. The results show that coherent beatspattern can be observed both in current and TMR. The proposed system consistingof two quantum dots attached to external leads, in which the dots' levels canbe tuned independently, can be realized experimentally to test this well knownphysical phenomenon. Finally, we also indicate possible practical applicationsof such device.
