Physicists at the University of Illinois at Urbana-Champaign announced they have observed a magnetic phenomenon called the "anomalous spin-orbit torque," or ASOT, for the first time. The team's findin...
Determination of the Upper Critical Field of a Single Crystal LiFeAs: The Magnetic Torque Study up to 35 Tesla
iron-based superconductor LiFeAs upper critical field anisotropy
2010/11/18
We report on the upper critical field Bc2 of a superconducting LiFeAs single crystal with
Tc ∼16K, determined from magnetic torque measurements in dc-magnetic fields up to 35T and
at temperatu...
Spin Torque Ferromagnetic Resonance Induced by the Spin Hall Effect
Spin Torque Ferromagnetic Resonance Spin Hall Effect
2010/11/22
We demonstrate that the spin Hall effect in a thin film with strong spin-orbit scattering
can excite magnetic precession in an adjacent ferromagnetic film. The flow of alternating current through a P...
