Nanomagnetism and Spintronics

About Our Research

Since mid-1990s the majority of Buhrman’s research activities have been in spintronics and thin film nanomagnetism. Contributions in this area include the pioneering, definitive demonstration of reversible spin transfer torque switching of thin film nanomagnets[i], the ability of spin transfer torque to excite nanoscale magnetic structures, including magnetic vortices[ii], into persistent microwave precession, and the early demonstration that spin torque can be successfully utilized with magnetic tunnel junctions[iii], despite the rather high tunnel current densities that are required.  These works played a seminal role in the initiation of the current worldwide industrial effort to realize a new high performance… Read more about our research
