Composition-dependent reversal of anomalous Hall effect in Co1-xPdx single layer
Source abstract
Abstract
We report a composition-dependent reversal of the anomalous Hall effect (AHE) in Co 1-xPd x single layers. As the Pd concentration increases, the AHE signal gradually diminishes and flips to negative polarity. Our study reveals that the competition between the extrinsic skew scattering and intrinsic contributions governing the sign reversal, accompany the rising Pd concentration. This work sheds light on the AHE mechanism in magnetic single layers with AHE reversal and paves the way for exploring novel spintronic phenomena.
