Direct Observation of Antimagnons with Inverted Dispersion
Hanchen Wang, Junfeng Hu, Wenjie Song +16
We report direct spectroscopic evidence of antimagnons, i.e., negative-energy spin waves identified by their signature inverted dispersion and left-handed precession with Brillouin…

Topological surface magnon-polariton in an insulating canted antiferromagnet
Weixin Li, Rundong Yuan, Fenglin Zhong +3
Excitation and control of antiferromagnetic magnon modes lie at the heart of coherent antiferromagnetic spintronics. Here, we propose a topological surface magnon-polariton as a ne…

Controlling spin currents with magnon interference in a canted antiferromagnet
Lutong Sheng, Anna Duvakina, Hanchen Wang +16
Controlling spin current lies at the heart of spintronics and its applications. The sign of spin currents is monotonous in ferromagnets once the current direction is determined. Sp…
