  Topological materials with large spin-orbit coupling and immunity to
disorder-induced symmetry breaking show great promise for efficiently
converting charge to spin. Here, we report that long-range disordered sputtered
WTex thin films exhibit local chemical and structural order as those of Weyl
semimetal WTe2 and conduction behavior that is consistent with semi-metallic
Weyl fermion. We find large charge-to-spin conversion properties and electrical
conductivity in thermally annealed sputtered WTex films that are comparable
with those in crystalline WTe2 flakes. Besides, the strength of unidirectional
spin Hall magnetoresistance in annealed WTex/Mo/CoFeB heterostructure is 5 to
20 times larger than typical SOT layer/ferromagnet heterostructures reported at
room temperature. We further demonstrate room temperature damping-like
SOT-driven magnetization switching of in-plane magnetized CoFeB. These large
charge-to-spin conversion properties that are robust in the presence of
long-range disorder and thermal annealing pave the way for industrial
application of a new class of sputtered semimetals.
