Spin-transfer and Topological Hall Effects as Novel Probes for Magnetic Disclinations in Frustrated Magnets
Ricardo Zarzuela, Jairo Sinova
Magnetic frustrated systems have resurged in spintronics as optimal candidates for hosting three dimensional topological solitons, such as Shankar skyrmions and 4-vortices, and…
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…
Spontaneous anomalous Hall effect arising from an unconventional compensated magnetic phase in a semiconductor
R. D. Gonzalez Betancourt, J. Zubáč, R. J. Gonzalez-Hernandez +12
The anomalous Hall effect, commonly observed in metallic magnets, has been established to originate from the time-reversal symmetry breaking by an internal macroscopic magnetizatio…
Defect-driven antiferromagnetic domain walls in CuMnAs films
Sonka Reimers, Dominik Kriegner, Olena Gomonay +17
Efficient manipulation of antiferromagnetic (AF) domains and domain walls has opened up new avenues of research towards ultrafast, high-density spintronic devices. AF domain struct…
Anomalous Hall antiferromagnets
Libor Smejkal, Allan H. MacDonald, Jairo Sinova +2
The Hall effect, in which current flows perpendicular to an applied electrical bias, has played a prominent role in modern condensed matter physics over much of the subject's histo…
Transport theory and spin-transfer physics for frustrated magnets
Ricardo Zarzuela, Jairo Sinova
We study the electron dynamics in magnetic conductors with frustrated interactions dominated by isotropic exchange. We present a transport theory for itinerant carriers built upon…
