Preparation and Properties of MgB2 Thin Films

The superconducting transition temperature of 140 nm ± 10 nm thin films on sapphire substrates, which were deposited by magnetron sputtering, was around 36 K. Using a magnetization technique, the film's critical current density was estimated as J C = 1.8 × 10 7 A/cm 2 at 10 K, J C = 8 × 10 6 A/...
