Separation of Artifacts from Spin-Torque Ferromagnetic Resonance Measurements of Spin-Orbit Torque for the Low-Symmetry van der Waals Semi-Metal ZrTe
Thow Min Cham, Saba Karimeddiny, Vishakha Gupta +2
We measure spin-orbit torque generated by exfoliated layers of the low-symmetry semi-metal ZrTe using the spin-torque ferromagnetic resonance (ST-FMR) technique. When the ZrTe$…
Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque
Saba Karimeddiny, Thow Min Cham, Daniel C. Ralph +1
We adapt Sagnac interferometry for magneto-optic Kerr effect measurements of spin-orbit-torque-induced magnetic tilting in thin-film magnetic samples. The high sensitivity of Sagna…
Resolving Discrepancies in Spin-Torque Ferromagnetic Resonance Measurements: Lineshape vs. Linewidth Analyses
Saba Karimeddiny, Daniel C. Ralph
When spin-orbit torques are measured using spin-torque ferromagnetic resonance (ST-FMR), two alternative ways of analyzing the results to extract the torque efficiencies -- linesha…
