Two Strategies to Measure Spin-Orbit-Torque Efficiency Acting on the Insulating Magnet LiAlFeO
Orion Smedley, Thow Min Jerald Cham, Daisy O'Mahoney +10
For insulating magnets, widely-used electrically-based techniques to measure spin-orbit-torque efficiency can suffer from poor signal-to-noise ratios and unwanted artifacts, while…
