We have measured a spin Hall conductivity in Ni60Cu40 that is comparable to the value we reported for Pt [1], using broadband FMR measurements of ferromagnet/nonmagnet bilayers that do not require patterning of the bilayer. In a series of samples with the layer structure Ta(3)/Py(3.5)/NixCu1-x(d)/Ta(3) (thickness in nm), we varied Ni fraction x for d = 10 nm and varied thickness d for x = 0.6, a composition with a critical temperature for magnetic ordering of 140 K. FMR measurements at room temperature showed a substantial SHE for all compositions we deposited, 0.3 ≤ x ≤ 0.75. For the thickness series at x = 0.6, we use the approach detailed in [1] to extract a spin diffusion length of (8.3 ± 0.4) nm and a spin Hall ratio of 1.05 ± 0.22. [1] Berger, A. J., et al.
