摘要：
We consider the spin torque induced by a current. owing ballistically through a magnetic domain wall. In addition to a global pressure in the direction of the electronic flow, the torque has an internal structure of comparable magnitude due to the precession of the electrons' spins at the "Larmor" frequency. As a result, the pro. le of the domain wall is expected to get distorted by the current and acquires a periodic sur-structure.
