Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque
Saba Karimeddiny, Thow Min Jerald Cham, Orion Smedley +2
Sagnac interferometry can provide a significant improvement in signal-to-noise ratio compared to conventional magnetic imaging based on the magneto-optical Kerr effect (MOKE). We s…
Anisotropic Gigahertz Antiferromagnetic Resonances of the Easy-Axis van der Waals Antiferromagnet CrSBr
Thow Min Jerald Cham, Saba Karimeddiny, Avalon H. Dismukes +3
We report measurements of antiferromagnetic resonances in the van der Waals easy-axis antiferromagnet CrSBr. The interlayer exchange field and magnetocrystalline anisotropy fields…
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…
Transverse and Longitudinal Spin-Torque Ferromagnetic Resonance for Improved Measurements of Spin-Orbit Torques
Saba Karimeddiny, Joseph A. Mittelstaedt, Robert A. Buhrman +1
Spin-torque ferromagnetic resonance (ST-FMR) is a common method used to measure spin-orbit torques (SOTs) in heavy metal/ferromagnet bilayer structures. In the course of a measurem…
