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…
Observation and Control of Chiral Spin Frustration in BiYIG Thin Films
Jinlong Wang, Hanchen Wang, Zhewen Xu +17
Chiral interactions within magnetic layers stabilize the formation of noncollinear spin textures, which can be leveraged to design devices with tailored magnetization dynamics. Her…
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…
