Query: High-throughput techniques for measuring the spin Hall effect   The spin Hall effect in heavy-metal thin films is routinely employed to
convert charge currents into transverse spin currents and can be used to exert
torque on adjacent ferromagnets. Conversely, the inverse spin Hall effect is
frequently used to detect spin currents by charge currents in spintronic
devices up to the terahertz frequency range. Numerous techniques to measure the
spin Hall effect or its inverse were introduced, most of which require
extensive sample preparation by multi-step lithography. To enable rapid
screening of materials in terms of charge-to-spin conversion, suitable
high-throughput methods for measuring the spin Hall angle are required. Here,
we compare two lithography-free techniques, terahertz emission spectroscopy and
broadband ferromagnetic resonance, to standard harmonic Hall measurements and
theoretical predictions using the binary-alloy series Au$_x$Pt$_{1-x}$ as
benchmark system. Despite being highly complementary, we find that all three
techniques yield a spin Hall angle with approximately the same $x$~dependence,
which is also consistent with first-principles calculations. Quantitative
discrepancies are discussed in terms of magnetization orientation and
interfacial spin-memory loss.
