摘要

Double-side superconducting MgB₂ films have been grown on double-side polished sapphire substrates by using hybrid physical-chemical vapor deposition method. The zero resistance temperatures T_C(0)>37 K and the critical current densities J_C(5 K,0 T)>3×10 ⁶ A/cm² have been achieved for both sides. In the first 8.73 G MgB₂ microstrip resonator fabricated by a double-side film, an unloaded Q value of 3400 at 11 K was obtained corresponding to surface resistance of 1.2 mΩ for the MgB₂/Al₂O₃ interface. By simply using a sapphire substrate with two polished holes, superconducting connection has been achieved for the double-side MgB₂ film. The results show potential applications for the superconducting MgB ₂ films in microwave and electronic devices.
