|Title:||Current-induced synchronized switching of magnetization|
|Published:||August 07, 2012|
|Abstract:||We propose a multilayer structure that allows a reduced switching current with maintaining high thermal stability of the magnetization. It consists of a perpendicular polarizer, a perpendicular free-layer, and an additional free-layer having in-plane magnetization. When the current runs perpendicular to the structure, the in-plane free-layer undergoes a precession motion and supplies an internal rf field to the perpendicular free-layer, resulting in a reduced switching current for one current polarity. For the other polarity, the in-plane free-layer almost saturates perpendicular to the plane and acts as another perpendicular polarizer, which also reduces the switching current.|
