Abstract
Based on the general requirement that all nature laws can be expressed in a tensor form, three new extraordinary galvanomagnetic effects in polycrystalline magnetic films, which differ from the known anomalous Hall effect and anisotropic magnetoresistance, are predicted. In general, a current perpendicular to a film can generate an electric field along the magnetization direction. Reversely, a current parallel to the magnetization can generate an electric field in the vertical direction of a film. The third extraordinary galvanomagnetic effect is that the longitudinal resistivity should depend on the magnetization component perpendicular to a film. One of the fingerprints of these effects is that the longitudinal resistance of a film is different when the current reverses its direction, and/or the in-plane longitudinal resistance is different when the perpendicular component of magnetization reverses its direction.
