Spin-orbit torque effects in all-electrical spin-wave spectroscopy experiments
José Solano Córdova, Jone Mencos, Richard Schlitz +10
Electrical excitation and detection of propagating spin waves are key elements of magnonic devices. While conventional antennas consisting of non-magnetic metals such as Au or Cu e…
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…
Quantifying thermal and driven magnon populations with femtosecond noise correlation spectroscopy
F. S. Herbst, M. A. Weiss, A. Leitenstorfer +5
Precise knowledge of the total number of magnons, including both coherent and incoherent (e.g. thermal) excitations, is imperative for the advancement of fundamental spin-wave phys…
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…
Coherent Microwave Driving of Domain Wall Depinning in a Ferrimagnetic Garnet
Hanchen Wang, Laura van Schie, Adam Erickson +6
Coherent control of domain wall dynamics offers a route to fast manipulation of magnetic textures beyond thermally activated motion. We demonstrate resonant excitation of linear an…
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…
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…
