Terahertz second harmonic generation driven by the unidirectional spin Hall magnetoresistance
We demonstrate THz second harmonic generation (SHG) in magnetic heterostructures arising from ultrafast spin Hall magnetoresistance (USMR). The interference between USMR and thermally driven contributions leads to an anisotropic dependence of the THz SHG. The USMR contribution can be separated from the others by analysing the angular dependence between the THz excitation pulse polarisation and the sample magnetisation direction on the THz SHG.
