Abstract

Magnetic frustration of spins often leads to nontrivial spin textures and anomalous Hall responses, but typically below the magnetic transition temperature. The authors observe a giant unconventional anomalous Hall conductivity in the triangularlattice antiferromagnet PdCrO2 well above its Neel temperature, attributed to spin cluster skew scattering.
