Revealing the Dominance of the Orbital Hall Effect over Spin in Transition Metal Heterostructures

J. L. Costa, E. Santos, J. B. S. Mendes +1

We study inverse spin and orbital Hall effects in 19 transition metals using spin-pumping driven by ferromagnetic resonance. Spin-to-charge conversion was measured in YIG/X(5), whi…
