Fabrication and characteristics of ferromagnetic single electron transistors

Abstract

A method for fabricating ferromagnetic single electron transistors with similar or different ferromagnetic electrodes is presented. In this method, the coercive fields of the electrodes can be easily distinguished. Calculations have been performed to optimize the device design and fabrication. Small values of island length, junction resistance and junction area are crucial for observing non-equilibrium spin accumulation in the island. (C) 2004 Elsevier B.V. All rights reserved.
