Vortex Polarity Switching by a Spin-Polarized Current [PDF]

Physical Review Letters, 2007
The spin-transfer effect is investigated for the vortex state of a magnetic nanodot. A spin current is shown to act similarly to an effective magnetic field perpendicular to the nanodot. Then a vortex with magnetization (polarity) parallel to the current polarization is energetically favorable.
