This i s primarily due to the fact that antiferromagnet order parameters\, in con trast to the ferromagnetic magnetization\, are only weakly coupled to magn etic fields\, and are hence difficult\, in conventional view\, to be probe d and manipulated. In this talk I will discuss some recent theoretical and experimental developments that counter this conventional wisdom\, in a cl ass of antiferromagnets that have stable noncollinear magnetic orders. As an introduction I will talk about the discovery of the anomalous Hall effe ct (AHE)\, which is the voltage perpendicular to the current or electric f ield direction in the absence of external magnetic fields and has been con ventionally assumed to exist only in ferromagnets\, in noncollinear antife rromagnets. I will then explain how the conventional spin Hall effect can be understood as a local response function involving spin density and char ge current in a quantum kinetic theory. Using this approach we are able to explain the recent experimental discovery of the time-reversal-symmetry-b reaking counterpart of the conventional SHE in the noncollinear antiferrom agnet Mn3Sn\, which we call the magnetic spin Hall effect (MSHE). Finally I will present our most recent findings on the giant field-like spin-orbit torques induced by the MSHE in Mn3Sn.\n\nCo-sponsored by: UCCS\n\nSpeaker (s): Hua Chen\, \n\nRoom: A204\, Bldg: Osborne Center for Science and Engi neering\, 1420 Austin Bluffs Pkwy\, Colorado Springs\, Colorado\, United S tates\, 80918 LOCATION:Room: A204\, Bldg: Osborne Center for Science and Engineering\, 14 20 Austin Bluffs Pkwy\, Colorado Springs\, Colorado\, United States\, 8091 8 ORGANIZER:dbozhko@uccs.edu SEQUENCE:0 SUMMARY:Magnetic Spin Hall Effects in Noncollinear Antiferromagnets URL;VALUE=URI:https://events.vtools.ieee.org/m/306482 X-ALT-DESC:Description: <br /><p>Despite the significant academic interest in them and their richness in nature\, antiferromagnets have always been o vershadowed by ferromagnets in real-life applications based on magnetism o r spintronics.
