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…
Giant interfacial Dzyaloshinskii-Moriya Interaction in perovskite La_{0.7}Sr_{0.3}MnO_{3} films
L. Yang, X. Zhang, H. Wang +14
The Dzyaloshinskii-Moriya interaction (DMI) plays a critical role in stabilizing topological spin textures, a key area of growing interest in oxide-based spintronics. While most of…
Persistent nodal magnon-photon polariton in ferromagnetic heterostructures
Zhuolun Qiu, Xi-Han Zhou, Hanchen Wang +2
Exceptional points with coalescence of eigenvalues and eigenvectors are spectral singularities in the parameter space, achieving which often needs fine-tuning of parameters in quan…
Orbital Hanle Magnetoresistance in a 3d Transition Metal
Giacomo Sala, Hanchen Wang, William Legrand +1
The Hanle magnetoresistance is a telltale signature of spin precession in nonmagnetic conductors, in which strong spin-orbit coupling generates edge spin accumulation via the spin…
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…
Nonlocal detection of interlayer three-magnon coupling
Lutong Sheng, Mehrdad Elyasi, Jilei Chen +13
A leading nonlinear effect in magnonics is the interaction that splits a high-frequency magnon into two low-frequency ones with conserved linear momentum. Here, we report experimen…
Non-Hermitian coherent coupling of nanomagnets by exchange spin waves
Hanchen Wang, Jilei Chen, Tao Yu +16
Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the i…
Magnon Trap by Chiral Spin Pumping
Tao Yu, Hanchen Wang, Michael A. Sentef +2
Chiral spin pumping is the generation of a unidirectional spin current in half of ferromagnetic films or conductors by dynamic dipolar stray fields from close-by nanomagnets. We fo…
Chiral spin-wave velocities induced by all-garnet interfacial Dzyaloshinskii-Moriya interaction in ultrathin yttrium iron garnet films
Hanchen Wang, Jilei Chen, Tao Liu +14
Spin waves can probe the Dzyaloshinskii-Moriya interaction (DMI) which gives rise to topological spin textures, such as skyrmions. However, the DMI has not yet been reported in ytt…
