Anomalous features of the conductivity and of the galvanomagnetic properties of vanadium dioxide in strong electric fields
The results of a study of the effect of a strong electric field on the kinetic properties of vanadium dioxide films are reported. The experimental method is based on the contact effects occurring in layered metal-insulator-semiconductor structures. The conductivity, magnetoresistance, and nonlinear resistance properties of the samples were found to behave anomalously in an electric field. The results are discussed in terms of the concept of a spontaneous macroscopic current in the films induced by the transition of the system to the toroidal current state.
