A Weyl semimetal is a new state of matter that host Weyl fermions asquasiparticle excitations. The Weyl fermions at zero energy correspond topoints of bulk band degeneracy, Weyl nodes, which are separated in momentumspace and are connected only through the crystal's boundary by an exotic Fermiarc surface state. We experimentally measure the spin polarization of the Fermiarcs in the first experimentally discovered Weyl semimetal TaAs. Our spin data,for the first time, reveal that the Fermi arcs' spin polarization magnitude isas large as 80% and possesses a spin texture that is completely in-plane.Moreover, we demonstrate that the chirality of the Weyl nodes in TaAs cannot beinferred by the spin texture of the Fermi arcs. The observed non-degenerateproperty of the Fermi arcs is important for the establishment of its exacttopological nature, which reveal that spins on the arc form a novel type of 2Dmatter. Additionally, the nearly full spin polarization we observed (~80%) maybe useful in spintronic applications.
