Journal ArticleDOI
Giant, unconventional anomalous Hall effect in the metallic frustrated magnet candidate, KV3Sb5.
Shuo-Ying Yang,Yaojia Wang,Brenden R. Ortiz,Defa Liu,Jacob Gayles,Jacob Gayles,Elena Derunova,Rafael González-Hernández,Rafael González-Hernández,Libor Šmejkal,Libor Šmejkal,Libor Šmejkal,Yulin Chen,Stuart S. P. Parkin,Stephen D. Wilson,Eric S. Toberer,Tyrel M. McQueen,Mazhar N. Ali +17 more
TL;DR: KV3Sb5 shows enhanced skew scattering that scales quadratically, not linearly, with the longitudinal conductivity, possibly arising from the combination of highly conductive Dirac quasiparticles with a frustrated magnetic sublattice, which allows the possibility of reaching an anomalous Hall angle of 90° in metals.
Journal ArticleDOI
Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets.
Libor Šmejkal,Libor Šmejkal,Libor Šmejkal,Rafael González-Hernández,Rafael González-Hernández,Tomas Jungwirth,Tomas Jungwirth,Jairo Sinova,Jairo Sinova +8 more
TL;DR: It is illustrated that accounting for the full magnetization density distribution instead of the simplified spin structure sheds new light on symmetry breaking phenomena in magnets and opens an alternative avenue toward low-dissipation nanoelectronics.
Journal ArticleDOI
Efficient Electrical Spin Splitter Based on Nonrelativistic Collinear Antiferromagnetism.

TL;DR: It is shown that a room-temperature metallic collinear antiferromagnet RuO_{2} allows for highly efficient spin-current generation, arising from anisotropically spin-split bands with conserved up and down spins along the Néel vector axis.
Journal ArticleDOI
Electrical switching of perpendicular magnetization in a single ferromagnetic layer

Crystal Hall effect in Collinear Antiferromagnets
TL;DR: In this paper, the robust crystal Hall effect mechanism arising from collinear antiferromagnetism combined with nonmagnetic atoms at non-centrosymmetric positions was identified.
