Superconducting and electrical properties of Mg-B structures formed by implantation of magnesium ions into the bulk boron followed by pulse plasma treatment

Superconducting regions of magnesium diboride (MgB2) on magnesium substrate were formed by the combined methods of ion implantation and transient annealing using three different ion fluences and three different energy density of Ar plasma pulses. The samples were characterized by Rutherford back scattering (RBS) and superconductivity detection techniques. The results of these characterizations are presented and discussed. The highest critical temperature observed TC=33.8 K.
