A new Mo--N phase has been prepared by rf reactive sputtering. The structure, as determined by x-ray analyses matches well with the hexagonal Mo/sub 2/C structure. The films were produced by reactively sputtering Mo in a gaseous N/sub 2/ atmosphere in an attempt to prepare thin films of the predicted high T/sub c/ superconductor MoN in the B1 phase. By further nitriding these Mo/sub 2/N films with NH/sub 3/ at 780 /sup 0/C for 24 h, they appeared more stoichiometric as determined by their superconducting properties. These films are superconducting T/sub c/ roughly-equal7 K and have high critical magnetic fields H/sub c/2(0) roughly-equal7.5 T. Varying both the temperature of the substrate between 500 and 900 /sup 0/C, and the power density did not effect the phase of the Mo--N compound.
