Direct Observation of Antimagnons with Inverted Dispersion
Hanchen Wang, Junfeng Hu, Wenjie Song +14
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…
Broad-Wavevector Spin Pumping of Flat-Band Magnons
Jinlong Wang, Hanchen Wang, Jilei Chen +11
We report the experimental observation of large spin pumping signals in YIG/Pt system driven by broad-wavevector spin-wave spin current. 280 nm-wide microwave inductive antennas of…
Observation of spin-wave moiré edge and cavity modes in twisted magnetic lattices
Hanchen Wang, Marco Madami, Jilei Chen +16
We report the experimental observation of the spin-wave moiré edge and cavity modes using Brillouin light scattering spectro-microscopy in a nanostructured magnetic moiré lattice c…
Long-distance propagation of high-velocity antiferromagnetic spin waves
Hanchen Wang, Rundong Yuan, Yongjian Zhou +8
We report on coherent propagation of antiferromagnetic (AFM) spin waves over a long distance (10 m) at room temperature in a canted AFM -FeO with the Dzyaloshin…
