  Based on ab initio calculations, we demonstrate that the ferromagnetic
CdO/EuO superlattice is a simple Weyl semimetal with two linear Weyl nodes in
the Brillouin zone, and the corresponding CdO/EuO quantum well realizes the
stichometric quantum anomalous Hall state without random magnetic doping. In
addition, a simple effective model is presented to describe the basic mechanism
of spin polarized band inversion in this system.
