Magnetism and anomalous transport in the Weyl semimetal PrAlGe: Possible route to axial gauge fields
<p>The file ManuscriptDataFiles.7z contains the raw experimental data from which the figures are made in the manuscript entitled "Magnetism and anomalous transport in the Weyl semimetal PrAlGe: Possible route to axial gauge fields" that appeared in npj Quantum Materials <strong>5</strong>, 5 (2020).</p> <p>Paper Abstract: In magnetic Weyl semimetals, where magnetism breaks time-reversal symmetry, large magnetically sensitive anomalous transport responses are anticipated that could be useful for topological spintronics. The identification of new magnetic Weyl semimetals is therefore in high demand, particularly since in these systems Weyl node configurations may be easily modified using magnetic fields. Here we explore experimentally the magnetic semimetal PrAlGe, and unveil a direct correspondence between easy-axis Pr ferromagnetism and anomalous Hall and Nernst effects. With sizes of both the anomalous Hall conductivity and Nernst effect in good quantitative agreement with first principles calculations, we identify PrAlGe as a system where magnetic fields can connect directly to Weyl nodes via the Pr magnetization. Furthermore, we find the predominantly easy-axis ferromagnetic ground state co-exists with a low density of nanoscale textured magnetic domain walls. We describe how such nanoscale magnetic textures could serve as a local platform for tunable axial gauge fields of Weyl fermions.</p>
Spatiotemporal determination of photoinduced strain in a Weyl semimetal
<p>The raw data of project-Spatiotemporal determination of photoinduced strain in a Weyl semimetal, including UEM bright image sequence, time delay series and HRTEM of WTe2 sample.</p>
Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals Co2MnGa and Co2MnAl
<p>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.</p>
