Abstract

We demonstrate a new and effective method of producing single-phase superconducting δ3-MoN nanowires from bundled Mo6SyIz (8.2 ≤ y + z ≤ 10) nanowire templates in the presence of ammonia gas. Magnetic susceptibility and electrical resistance measurements confirm single-phase material synthesis. Measurements of four-contact resistance on single wires with diameters above 100 nm in a magnetic field are used to determine the critical field, while diameter dependence and magnetization measurements are used to investigate the homogeneity of the nanowires.
