Turn‐On of Current‐Induced Spin Torque Upon Non‐collinear Antiferromagnetic Ordering in Delafossite PdCrO <sub>2</sub>
Measurements of the current-induced spin torque produced by the delafossite antiferromagnet PdCrO<sub>2</sub> and acting on an adjacent ferromagnetic permalloy layer are reported. The spin torque increases strongly as the temperature is reduced through the Néel temperature, when the PdCrO<sub>2</sub> transitions from a paramagnetic phase to a non-collinear antiferromagnetic state. This result is qualitatively consistent with density functional theory calculations regarding how spin-current generation changes upon antiferromagnetic ordering in PdCrO<sub>2</sub>.
