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…
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…
Altermagnetism: spin-momentum locked phase protected by non-relativistic symmetries
Libor Šmejkal, Jairo Sinova, Tomas Jungwirth
The search for novel magnetic quantum phases, phenomena and functional materials has been guided by relativistic magnetic-symmetry groups in coupled spin and real space from the da…
Giant and tunneling magnetoresistance effects from anisotropic and valley-dependent spin-momentum interactions in antiferromagnets
Libor Šmejkal, Anna Birk Hellenes, Rafael González-Hernández +2
Giant or tunneling magnetoresistance are physical phenomena used for reading information in commercial spintronic devices. The effects rely on a conserved spin current passing betw…
