摘要
I derive a new analytic expression for the critical threshold current needed to switch a single-domain magnet by means of the transfer of spin momentum from a static magnet. It is the first such expression which takes significant account of the electron structure of the constituent ferromagnets. It is valid for a class of pillar compositions and geometries commonly used in experiments. (C) 2003 Elsevier B. V. All rights reserved.
