Abstract
We report about the anomalous Hall effect in metallic alloys measured using terahertz time-domain spectroscopy. In this way, we succeeded in revealing ultrafast dynamics of the anomalous Hall effect which accompanies the sub-100-ps optically induced magnetization reversal in a GdFeCo alloy. The experiments demonstrate the ability to control currents at terahertz frequencies in spintronic devices magnetically and ultrafast.
