A Type II Weyl fermion semimetal has been predicted in MoxW1−xTe2, but it awaits experimental evidence. Here, Belopolski et al. observe a topological Fermi arc in MoxW1−xTe2, showing it originates from a Type II Weyl fermion and offering a new platform to study novel transport phenomena in Weyl semimetals.
