We report crystal growth of cubic ReN_x prepared by molecular beam pitaxy. There are less reports about the growth of cubic ReN_x. Although this material is indicated as a superconductor, there are no clear results of both Meissner effect and zero resistivity. While we investigate complex nitride system with lanthanoid, we found that the cubic ReN_x is stabilized by Pr addition, and the film shows the both Meissner effect and zero resistivity.
