Description
We study the effect of magnetic anisotropy in a single electron transistor with ferromagnetic electrodes and a non-magnetic island. We identify the variation $δμ$ of the chemical potential of the electrodes as a function of the magnetization orientation as a key quantity that permits to tune the electrical properties of the device. Different effects occur depending on the relative size of $δμ$ and the charging energy. We provide preliminary quantitative estimates of $δμ$ using a very simple toy model for the electrodes.
