Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque Open
Sagnac interferometry can provide a substantial improvement in signal-to-noise ratio compared to conventional magnetic imaging based on the magneto-optical Kerr effect. We show that this improvement is sufficient to allow quantitative meas…

Anisotropic Gigahertz Antiferromagnetic Resonances of the Easy-Axis van der Waals Antiferromagnet CrSBr Open
We report measurements of antiferromagnetic resonances in the van der Waals easy-axis antiferromagnet CrSBr. The interlayer exchange field and magnetocrystalline anisotropy fields are comparable to laboratory magnetic fields, allowing a ri…

Separation of Artifacts from Spin‐Torque Ferromagnetic Resonance Measurements of Spin‐Orbit Torque for the Low‐Symmetry Van der Waals Semi‐Metal ZrTe <sub>3</sub> Open
Spin‐orbit torques generated by exfoliated layers of the low‐symmetry semi‐metal ZrTe 3 are measured using the spin‐torque ferromagnetic resonance (ST‐FMR) technique. When the ZrTe 3 has a thickness greater than about 10 nm, artifacts due …

Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque Open
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 Sagnac interferometry permits for the first time optical quantif…

Strong, Temperature-Dependent Spin-Orbit Torques in Heavy Fermion YbAl$_3$ Open
The use of current-generated spin-orbit torques[1] to drive magnetization dynamics is under investigation to enable a new generation of non-volatile, low-power magnetic memory. Previous research has focused on spin-orbit torques generated …
