Resumen:
We report on the superconducting properties of nanocrystalline molybdenum nitride thin films grown by reactive DC sputtering at room temperature with a N2:Ar mixture. Thin films grown using 5% N2 concentration display Tc = 8 K, which is gradually reduced to 5.8 K for 30% N2 concentration, producing changes in nitrogen stoichiometry of the samples from Mo2N to Mo2N1+x (0 ≤ x 40%).
