Our research is focused on the exploration of novel magnetic & spintronic materials for memory, logic, and HDD storage applications. We concentrate on the development of thin films & nanoscale devices that will enable improved energy efficiency, non-volatility, and scalability to ever-decreasing dimensions. Current research efforts include crystallographic & microstructural characterization of perpendicular magnetic recording media, materials for spin hall effect devices, spin transfer torque magneto-resistive random access memory (STT-MRAM), and magnetic interactions in soft nanogranular composite thin films.
