Abstract:
A method of forming a superconductor film, comprising:filling gas in a sealed container having therein a magnesium target, a boron target and one or more substrates facing the targets; applying voltage between the magnesium target and the substrate to discharge the gas and between the boron target and the substrate to discharge the gas; and forming a film of a MgB2 compound on the substrates, the MgB2 compound generated from reaction of magnesium ejected in a sputtering process at the magnesium target and boron ejected in a sputtering process at the boron target, wherein the film is formed on the substrate with a temperature of 300Â° C.-390Â° C., and the film of the MgB2 compound has characteristics of a superconductor as-grown film without being annealed once the film has been formed.
