摘要

Using a micromagnetics calculation, we explore the properties of a submicron magnetic square with microwave assisted switching. For a 10x160x160 nm(3) structure of Fe-Ti-N, there are three particular stable magnetic states for reversal fields up to -320 Oe. One can switch between these different states by adding a microwave field. The strength and the frequency of the microwave field determine the final state. A microwave field of up to 30 Oe does not change the magnetization. Fields of 50 to 75 Oe result in an intermediate state, while larger microwave fields produce a reversed ground state.
