We report the growth of ZnS nanowires doped with cobalt using a one-step thermal evaporation method. The magnetism of the nanowires was maintained at room temperature, and the saturated magnetization increased with cobalt contents. Current-voltage measurements of a single nanowire showed not only a linear relationship, which implies Ohmic contacts of nanowire devices, but also tunable conductivities by doping concentration.
