Dependence of the superconducting transition temperature of single- and polycrystalline MgB2 on hydrostatic pressure

S. Deemyad, T. Tomita, J. J. Hamlin +6

The dependence of Tc for MgB2 on purely hydrostatic or nearly hydrostatic pressure has been determined to 23 GPa for single-crystalline and to 32 GPa for polycrystalline samples, a…
