Visualizing Microwave-Driven Dynamics of Antiskyrmions and Surface Skyrmions
Zhuolin Li, Daisuke Nakamura, Spencer Reisbick +9
Microwaves provide coherent access to low-energy excitations and serve as effective probes of high-frequency spin dynamics in quantum and magnetic systems. For topological spin tex…
Anisotropy-dependent decay of room temperature metastable skyrmions and a nascent double- spin texture in CoZnMn
J. S. White, V. Ukleev, L. Yu +3
Chiral cubic Co-Zn-Mn magnets exhibit diverse topological spin textures, including room-temperature skyrmion phases and robust far-from-equilibrium metastable states. Despite recen…
Nonreciprocal transport in a room-temperature chiral magnet
Daisuke Nakamura, Mu-Kun Lee, Kosuke Karube +4
Chiral magnets under broken time-reversal symmetry can give rise to rectification of moving electrons, called nonreciprocal transport. Several mechanisms, such as the spin-fluctuat…
Spontaneous topological Hall effect induced by non-coplanar antiferromagnetic order in intercalated van der Waals materials
H. Takagi, R. Takagi, S. Minami +14
In ferromagnets, electric current generally induces transverse Hall voltage in proportion to magnetization (anomalous Hall effect), and it is frequently used for electrical readout…
Nonreciprocal Phonon Propagation in a Metallic Chiral Magnet
T. Nomura, X. -X. Zhang, R. Takagi +7
The phonon magnetochiral effect (MChE) is the nonreciprocal acoustic and thermal transports of phonons caused by the simultaneous breaking of the mirror and time-reversal symmetrie…
Task-adaptive physical reservoir computing
Oscar Lee, Tianyi Wei, Kilian D. Stenning +11
Reservoir computing is a neuromorphic architecture that potentially offers viable solutions to the growing energy costs of machine learning. In software-based machine learning, neu…
Highly anisotropic geometrical Hall effect via f-d exchange fields in doped pyrochlore molybdates
Hikaru Fukuda, Kentaro Ueda, Yoshio Kaneko +6
When a conduction electron couples with a non-coplanar localized magnetic moment, the realspace Berry curvature is exerted to cause the geometrical Hall effect, which is not simply…
Doping control of magnetic anisotropy for stable antiskyrmion formation in schreibersite (Fe,Ni)P with symmetry
Kosuke Karube, Licong Peng, Jan Masell +6
Magnetic skyrmions, vortex-like topological spin textures, have attracted much interest in a wide range of research fields from fundamental physics to spintronics applications. Rec…
Spin-wave spectroscopy on Dzyaloshinskii-Moriya interaction in room-temperature chiral magnets hosting skyrmions
R. Takagi, D. Morikawa, K. Karube +8
Propagation character of spin wave was investigated for chiral magnets FeGe and Co-Zn-Mn alloys, which can host magnetic skyrmions near room temperature. On the basis of the freque…
