Model of the magnon Kerr effect in a highly anisotropic ferromagnet
Davit Petrosyan, Hiroki Matsumoto, Hanchen Wang +3
The magnon Kerr effect is a nonlinear phenomenon that occurs universally in any ferromagnet with finite magnetic anisotropy. It manifests itself as a magnon population-dependent ch…
Challenges in orbital current-driven domain wall motion in light metal/ferrimagnet heterostructures
Min-Gu Kang, Jaerin Kim, Benjamin J. Jacot +2
Recent advances in spintronics suggest that orbital Hall currents generated by charge injection in light metals can provide nonequilibrium angular momentum without relying on stron…
Charge-to-spin conversion in epitaxial and polycrystalline Bi and Bi/Ag layers
Federica Nasr, Emir Karadža, Santos F. Alvarado +9
Bi is predicted to be an efficient generator of spin-orbit torques (SOTs), with charge-to-spin conversion efficiency comparable to those of prototypical heavy metals, such as Ta, W…
Coherent and Dissipative Spin Torques in Quantum Dots: A Unified Framework for Quantum Spin Dynamics
Dominic Ruckert, Stepan Kovarik, Richard Schlitz +4
The manipulation of single spins through spin-polarized tunneling opens new routes for quantum control at the atomic scale. We present a theoretical framework describing spin-trans…
High-mobility inertial domain walls driven by spin-transfer torque in a ferrimagnetic spinel oxide
Mingxing Wu, Shilei Ding, Laura van Schie +8
Efficient electrical manipulation of domain walls is key to developing magnetic devices with fast switching capabilities and low energy consumption. Here we demonstrate Bloch-type…
Disambiguating electrical detection of magnetization dynamics in magnetic insulators
Hanchen Wang, William Legrand, Shangyuan Wang +6
Electrical detection of magnetization dynamics in magnetic insulators underpins both fundamental studies of magnon transport and the development of low-loss magnonic devices. In he…
Loop-gap resonators achieving strong magnon-photon coupling in magnetic insulator thin films
Francesca Zanichelli, Davit Petrosyan, Hanchen Wang +4
Magnon-photon hybrid systems consisting of a three-dimensional electromagnetic resonator and a bulk magnetic insulator constitute the standard experimental platform in cavity magno…
Magnon Kerr Effect in a Magnetic Thin Film Strongly Coupled to a Microwave Resonator
Davit Petrosyan, Hiroki Matsumoto, Hanchen Wang +4
Progress in cavity magnonics relies on tunable nonlinearities in magnon-photon interactions for controlling magnon dynamics and frequency conversion. Here, we demonstrate the magno…
Dynamical Stabilization of Inverted Magnetization and Antimagnons by Spin Injection in an Extended Magnetic System
Emir Karadza, Hanchen Wang, Niklas Kercher +4
Dynamical perturbations can modify the energy landscape of a physical system, such that unstable equilibrium configurations become stable when subject to an external drive. The mag…
Generating unconventional spin-orbit torques with patterned phase gradients in tungsten thin films
Lauren J. Riddiford, Anne Flechsig, Shilei Ding +7
A key aim in spintronics is to achieve current-induced magnetization switching via spin-orbit torques without external magnetic fields. For this, the focus of recent work has been…
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…
