Abstract
Coherent-source THz spectroscopy was employed for measuring the Faraday rotation angle of Mn { mathbf {2-x}}PtSn films (x = 0; 0.2). In the THz experiments, we observe clear signatures of an anomalous Hall state, while any indications of the so-called topological Hall effect recently observed in these magnetically disordered systems in dc measurements-are absent. This demonstrates that the charge scattering mechanisms, responsible for the two phenomena, possess very different time scales: the anomalous Hall state is governed by the scattering process with the rates above THz frequencies, while the electron interaction, providing the topological Hall, possesses very low characteristic time scales.
