Superconducting MgB2 thin films have been fabricated by 80 keV B-11 ion implantation into commercial Mg ribbon with B-11 doses up to 10(18) ions/cm(2), followed by thermal annealing at 500 degreesC. Temperature dependent dc magnetization measurements confirmed superconducting phase transitions between 11 and 18 K for samples containing nanocrystalline MgB2 grains embedded in Mg substrate with a small amount of MgO inclusion.
