Superconducting nanowires, with a critical temperature of 5.2K, have been synthesized using an ion-beam-induced deposition, with a gallium focused ion beam and tungsten carboxyl, W(CO)6, as precursor. The films are amorphous, with atomic concentrations of about 40%, 40%, and 20% for W, C, and Ga, respectively, 0K values of the upper critical field and coherence length of 9.5T and 5.9nm, respectively, are deduced from the resistivity data at different applied magnetic fields. The critical current density is Jc=1.5×105A∕cm2 at 3K. This technique can be used as a template-free fabrication method for superconducting devices.
