New Galvanomagnetic Effects of Polycrystalline Magnetic Films

Abstract

Within the linear response of polycrystalline magnetic films to electric currents, a general analysis predicts three new galvanomagnetic effects originated from the two-dimensional nature of the films. These new galvanomagnetic effects, which differ from the conventional extraordinary Hall effect and anisotropic magnetoresistance, are follows. 1) The longitudinal resistivity depends linearly on the magnetization component perpendicular to a film. 2) A current parallel to the magnetization can generate an electric field in the vertical direction of a film. 3) A current perpendicular to a film can generate an electric field along the magnetization direction.
