Description
MgB2 thin films were deposited by the ablation technique utilizing high-energy pulsed ion beam of 700 keV and 10 J/cm2 pulse. The target plates are fabricated by sintering MgB2 stoichiometric powder at 1100 oC being encapsulated. The MgB2 films are preferentially c-axis oriented on r-cut Al2O3 substrates, in spite of the high quenching rate. A possible growth of MgB2 single crystals with hexagonal shape and 1 μm in size is observed on the film surface. Upon conducting post-annealing at 600 oC, the films become superconducting with the transition temperature T c = 11 K
