We discuss the transport properties of small magnetic double barrier structures in terms of the orthodox theory of single-electron tunneling for non-vanishing spin-relaxation times. The magnetoresistance of the system is enhanced for slow spin-relaxation in the island due to reduced mixing of the spin-channels. The spin accumulation can be detected by the long-time transient response, which is dominated by the spin dynamics.
