Abstract
We discuss the transport properties of small magnetic double barrier struct ures in terms of the orthodox theory of single-electron tunneling for non-v anishing spin-relaxation times. The magnetoresistance of the system is enha nced for slow spin-relaxation in the island due to reduced mixing of the sp in-channels. The spin accumulation can be detected by the long-time transie nt response, which is dominated by the spin dynamics. (C) 1999 Elsevier Sci ence B.V. All rights reserved.
