Observation of the crossover between metallic and insulating regimes of the spin Hall effect
Abstract
Intense research efforts have provided mechanistic insight into the spin and anomalous Hall effects in metallic samples, but the effect of extrinsic defects is not yet understood. Here, a scaling law describing the spin Hall response of PtO films with increasing oxygen levels reveals an analogy with the anomalous Hall effect in the insulating regime.
