Our current research involves studying electron spin dynamics in thin film magnetic nanostructures. Much of our work focuses on the spin transfer torque (STT) and on the STT-induced magnetization domain reversal and high frequency (GHz) magnetization dynamics of these nanomagnets. STT-induced magnetic dynamics have immense applicability in both the evolution of memory technology as well as in the development of highly tunable microwave oscillators.
To that end, we are pursuing an understanding of the possible types of magnetization dynamics allowed by the spin transfer torque in different geometries and in different materials, the influence of noise on magnetization dynamics, and lastly, the role of the magnetic damping.
We have active collaborations with the groups of Dan Ralph and Bruce van Dover.
Our work makes active use of the Cornell NanoFabrication Facility (CNF), The Center for Nanoscale Systems (CNS), and The Cornell Center for Materials Research (CCMR).
