Probing polarization-tunable sub-terahertz spin pumping in bimodal α-Fe2O3/Pt

Abstract Hematite (α-Fe2O3) is an insulating antiferromagnet possessing a room temperature canted phase induced by the super-exchange Dzyaloshinskii-Moriya Interaction (DMI), resulting in enhanced spin pumping and spin transport over uniaxial antiferromagnets. In this work we resonantly excite the q...
