Weyl semimetals are playing a major role in condensed matter physics due toexotic topological properties, and their coexistence with ferromagnetism maylead to enhanced spin-related phenomena. Here, the inverse spin Hall effect(ISHE) in the ferromagnetic Weyl-semimetal Heusler alloy Co$_2$MnGa wasinvestigated at room temperature by means of electrical spin injection inlateral spin valve structures. Spin transport properties such as spinpolarization and spin diffusion length in this material were preciselyextracted in order to estimate the spin Hall angle $\theta_{\textrm{SH}}$,which was found to be $-0.19\pm0.04$ and is among the highest reported for aferromagnet. Although this value is on the same order of magnitude of knownheavy metals, the significantly higher resistivity of Co$_2$MnGa implies animprovement on the magnitude of detection voltages, while its ferromagneticnature allows controlling the intensity of SHE through the magnetizationdirection. It was also shown that Onsager's reciprocity does not hold for thissystem, which is in part attributable to a different spin-dependent Hallconductivity for spin-up and spin-down carriers.
