资源简介：
We study ultrafast optically driven spin injection from thin films of the magnetic Weyl semimetals Co<sub>2</sub>MnGa and Co<sub>2</sub>MnAl into an adjacent Pt layer by means of terahertz emission spectroscopy. The following datasets are provided: THz waveforms, THz emission-signal amplitudes (rms) vs pump power, scaled THz signals as a figure of merit in terms of spin-injection efficiency, corresponding broadband spectra and extracted spin currents.
