Low temperature synthesis of MgB2

Abstract:

We report the synthesis of MgB 2 with bulk superconducting properties by conventional solid state methods at temperatures as low as 550°C. Mg deficiencies of the type Mg 1-xB 2 were tested. T c was found to decrease by about 1 K at large x, though the amount of nonstoichiometry, if any, is likely to be very small. For specific processing conditions, indications of the 25-30 K transition often seen in thin films were seen in the bulk materials. The lower temperature transition may be associate...
