| contents | Magnetic miniaturized nanostructures hold great promise for current and future microwave technologies due to their magnetization dynamics in the GHz frequency range. This work presents a method for investigating reconfigurable microwave properties using a novel hexagonal nanomagnet structure. Micromagnetic simulations are employed to investigate the magnetic static and dynamic properties of the nanomagnets. A simple field initialization method is used to examine two distinct magnetic remanent states in each sample. A nanosecond-width magnetic pulse field can be applied to tune the unique magnetization dynamics parameters corresponding to the different remanent states. Find that for both single-layer and multilayer nanomagnets, there is a notable frequency shift in the sub-GHz and GHz regions between the two distinct magnetic remanent states. |
