Symmetry-DependentUltrafast Spin Currents and THzEmissions in Noncollinear Antiferromagnetic Mn3Pt/Pt Heterostructures

Abstract Noncollinear antiferromagnets (NCAFs) provide a symmetry-rich platform for ultrafast spintronics, where light-driven spin currents are governed by both crystallographic orientation and magnetic symmetry. Here, we investigate femtosecond-laser-induced terahertz (THz) emis...
