This work examines the conductivity properties of point contact magnetic tunnel junctions taking into account gradients of the electrochemical potentials at the ferromagnetic metal/dielectric interface. The calculations were carried out for spin-polarized currents at arbitrary ratio the point magnetic tunnel junction size and the mean free paths of conduction electrons under the applied voltage conditions. Current-voltage characteristics were obtained for symmetrical and asymmetrical point junctions.
