The criterion for election is exceptional contributions to the physics enterprise; e.g., outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education. Fellowship is a distinct honor signifying recognition by one's professional peers.
For his fundamental contributions to the experimental studies of the spin-torque oscillators, their interactions, and collective states, and for the development of new quantitative experimental methods for the investigation of magnetization dynamics in thin films and nanostructures.
