Spin dependent single electron tunneling in a ferromagnetic double junction is investigated theoretically in the limit of incoherent sequential tunneling. The junction consists of a small nonmagnetic metallic grain with discrete energy levels, which is connected to two ferromagnetic electrodes. We have developed a new theoretical model taking into account charge as well as spin degrees of freedom. The model allows us to investigate new phenomena such as spin accumulation and spin fluctuations.
