| Summary:
We report measurements of the current-induced spin torque produced by the
delafossite antiferromagnet PdCrO2 and acting on an adjacent ferromagnetic
permalloy layer. The spin torque increases strongly as the temperature is
reduced through the Neel temperature, when the PdCrO2 transitions from a
paramagnetic phase to a noncollinear antiferromagnetic state. This result is
qualitatively consistent with density functional theory calculations regarding
how spin-current generation changes upon antiferromagnetic ordering in PdCrO2.
