B1-phase MoN films, prepared by sputtering, are annealed under a pressure of 6 GPa at temperatures between 600 and 1100 /sup 0/C for 8 h. The B1-phase MoN is converted mainly to hexagonal-phase and partly to tetragonal-phase Mo/sub 2/N when annealed at temperatures above 750 /sup 0/C. A residual phase was observed only at an annealing temperature of 600 /sup 0/C. The T/sub c/o (the onset of T/sub c/) of 1000 /sup 0/C-annealed films was 14.9 K; this is the maximum value found in the literature for the Mo-N system.
