We investigate the spin Hall effect of W-Hf thin films, which exhibit a phasetransition from a segregated phase mixture to an amorphous alloy below 70% W.The spin Hall angle was determined with a planar harmonic Hall voltagetechnique. Due to the accompanying jump in resistivity, the spin Hall angleshows a pronounced maximum at the composition of the phase transition. The spinHall conductivity does, however, reduce from W to Hf with a weak discontinouityacross the phase transition. The maximum spin Hall angle of $\theta_\mathrm{SH}= -0.25$ is obtained for amorphous W$_{0.7}$Hf$_{0.3}$. A detailed comparisonwith spin Hall conductivities calculated from first principles for hcp, fcc,and bcc solid solutions provides valuable insight into the alloying physics ofthis binary system.
