Twist-Tuned Magnonic Nanocavity Mode in a Trilayer Moiré Superlattice
Tianyu Yang, Gianluca Gubbiotti, Marco Madami +2
The concept of moiré superlattices has recently been introduced into the field of magnonics, enabling unprecedented control over spin-wave propagation and confinement in nanoscale…
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…
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…
Magnon confinement in a nanomagnonic waveguide by a magnetic Moiré superlattice
Jilei Chen, Marco Madami, Gianluca Gubbiotti +1
The study of moiré superlattices has revealed intriguing phenomena in electronic systems, including unconventional superconductivity and ferromagnetism observed in magic-angle bila…
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…
