| 中文摘要 | A current-induced magnetization switching has been observed in a microscale ring-shaped magnetic tunnel junction having an alumina barrier, which showed a tunneling magnetoresistance ratio of 37% and a resistance-area product of 175 Omega mu m(2). Several metastable magnetization states were observed during field driven switching of this junction. Preparing the junction in one of these metastable states allowed a current-induced switching to take place at current densities 2 orders of magnitude lower than conventional switching values. Micromagnetic modeling indicates that the effect was solely due to Oersted field switching, which explains the markedly different forms of the current- and field-driven hysteresis loops. |
