Abstract
Using a micromagnetics calculation, we explore the properties of a submicron magnetic square with microwave assisted switching. For a 10×160×160 nm3 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.
