We experimentally investigate spin-polarized transport between aferromagnetic Ni electrode and a surface of Weyl semimetal, realized in a thickWTe$_2$ single crystal. For highly-transparent Ni-WTe$_2$ planar junctions, weobserve non-Ohmic $dV/dI(I)$ behavior with an overall increase of differentialresistance $dV/dI$ with current bias, which is accomplished by current-inducedswitchings. This behavior is inconsistent with trivial interface scattering,but it is well known for spin-polarized transport with magnon emission. Thus,we interpret the experimental results in terms of spin wave excitation in spintextures in the WTe$_2$ topological surface states, which is supported by theobtained magnetic field and temperature $dV/dI(I)$ dependencies.
