Kresch, A; Vistoli, A (2004). On coverings of Deligne-Mumford stacks and surjectivity of the Brauer map. Bulletin of the London Mathematical Society, 36(2):188-192.
The paper proves a result on the existence of finite flat scheme covers of Deligne–Mumford stacks. This result is used to prove that a large class of smooth Deligne–Mumford stacks with affine moduli space are quotient stacks, and in the case of quasi-projective moduli space, to reduce the question to a classical question on Brauer groups of schemes.
