The fabrication of an as-grown MgB2 crystalline thin film at a low temperature of 270°C was discussed. The fabrication was done using an in-plane-lattice near-matched TiZr buffer layer grown on a sapphire Al 2O3 (0001) surface. The critical temperature and the superconductivity critical current density of MgB2/TiZr/Al 2O3 was found to be higher than the MgB 2/Al2O3. The experiments show that the in-plane-lattice near-matched TiZr buffer layer served for the fabrication of the as-grown MgB2crystalline film.
