12 Jan 2007 | | Journal: | Phys. Stat. Sol. (c) 3, 4231 (2006) | | Subject: | Mesoscopic Systems and Quantum Hall Effect | | Abstract: | We study the effect of magnetic anisotropy in a single electron transistor with ferromagnetic electrodes and a non-magnetic island. We identify the variation $delta mu$ 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 $delta mu$ and the charging energy. We provide preliminary quantitative estimates of $delta mu$ using a very simple toy model for the electrodes. | | Source: | arXiv, cond-mat/0701273 | | Services: | Forum | Review | PDF | Favorites | |
