Influence of magnetism, strain and pressure on the band topology of EuCdAs
Adrian Valadkhani, Mikel Iraola, Axel Fünfhaus +4
Motivated by the wealth of proposals and realizations of nontrivial topological phases in EuCdAs, such as a Weyl semimetallic state and the recently discussed semimetallic…
Anisotropic long-range spin transport in canted antiferromagnetic orthoferrite YFeO
Shubhankar Das, A. Ross, X. X. Ma +15
In antiferromagnets, the efficient propagation of spin-waves has until now only been observed in the insulating antiferromagnet hematite, where circularly (or a superposition of pa…
Spin eigen-excitations of an antiferromagnetic skyrmion
Volodymyr P. Kravchuk, Olena Gomonay, Denis D. Sheka +5
We theoretically predict and classify the localized modes of a skyrmion in a collinear uniaxial antiferromagnet and discuss how they can be excited. As a central result, we find tw…
Néel Spin Orbit Torque driven antiferromagnetic resonance in MnAu probed by time-domain THz spectroscopy
N. Bhattacharjee, A. A. Sapozhnik, S. Yu. Bodnar +11
We observe the excitation of collective modes in the THz range driven by the recently discovered Néel spin-orbit torques (NSOT) in the metallic antiferromagnet MnAu. Temperat…
Skyrmion production on demand by homogeneous DC currents
Karin Everschor-Sitte, Matthias Sitte, Thierry Valet +2
Topological magnetic textures - like skyrmions - have become a major player in the design of next-generation magnetic storage technology due to their stability and the control of t…
Very large magnetoresistance in FeTaS single crystals
Will J. Hardy, Chih-Wei Chen, A. Marcinkova +4
Magnetic moments intercalated into layered transition metal dichalcogenides are an excellent system for investigating the rich physics associated with magnetic ordering in a strong…
