Abstract

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.
