We have grown MgB2 thin films using RF magnetron sputtering combined with a pocket heater. This technique relies on a low-pressure environment for sputter deposition of boron and a high-pressure environment for thermal evaporation of Mg. We have obtained superconducting MgB2 thin films using substrate temperatures of 480-540degC and Mg furnace temperatures of 730-750degC. The Tc onset of the thin films increased from 21.6 K to 35 K with increasing substrate temperature due to better… CONTINUE READING
