A magnetoelectronic device concept in which a spin-current pulse can induce a rapid precessional reversal of the magnetization of thin film nanomagent was discussed. The spin switching speed was determined by the precession frequency of the magnetization of a thin film element's demagnetization field. It was observed that thin films with perpendicular anisotropy can be realized in multilayer, such as Co or Fe layered with Pt or Pd 13 or by using shape anisotropy. Results from the micromagnetic simulations show that switching occurs above a threshold pulse current and cab faster than 50 ps.
