Microwave Properties Of Magnetic Nanowires Arrays, Daniel Adams

Innovate UNO

This study focused on examining high-frequency properties of magnetic nanowire arrays. The microwave was produced by a Vector Network Analyzer (VNA) and transmitted through coplanar waveguides (CPW). The CPWs are 300 µm long with signal line width of 20 µm, ensuring minimum losses due to radiation. CPWs were fabricated through the photolithography process. The magnetic nanowires were fabricated through e-beam lithography on top of the CPW. The VNA was used to feed the CPW and measurements of the FMR absorption allowed us to understand the effect of interaction between nanowires on their dynamic properties.
