Spin current from sub-terahertz-generated antiferromagnetic magnons
Nature, Published online: 27 January 2020; doi:10.1038/s41586-020-1950-4
Pure spin currents are simultaneously generated and detected electrically through sub-terahertz magnons in the antiferromagnetic insulator Cr2O3, demonstrating the potential of magnon excitations in antiferromagnets for high-frequency spintronic devices.
