Event Details

In recent years there has been a revival of interest in the phenomena of Ferro-magnetic Resonance (FMR) driven in part by the development of e-beam lithography as a tool to make magnetic nano structures but also due to the discovery of the spin Hall effect. Demagnetization effects dominate the behavior of FMR at microwave frequencies and we will review methods used to calculate the response of thin films as well as arbitrarily shaped objects and apply the latter to various patterned permalloy arrays. We will conclude with a discussion of some experiments that employ the spin Hall effect to study FMR.
