Abstract
Non-adiabatic correction to spin transfer torque arising from fast-varying spin texture is calculated treating conduction electron fully quantum mechanically. The torque is non-local in space, and is shown to equivalent to a force (due to momentum transfer) acting on the center of mass of the texture. Another kind of force exists in the adiabatic regime, and is identified to be of topological origin. These forces are shown to be the counter reaction of electric transport properties, resistivity and Hall effect, respectively.
