High Pressure Study of Structural Phase Transitions and Superconductivity in La1.48Nd0.4Sr0.12CuO4
M. K. Crawford, R. L. Harlow, S. Deemyad +8
We have determined the crystal structures and superconducting transition temperatures of La1.48Nd0.4Sr0.12CuO4 under nearly hydrostatic pressures in diamond anvil cells to 5.0 GPa…

Pressure dependence of the upper critical field of MgB2 and of YNi2B2C
H. Suderow, V. G. Tissen, J. P. Brison +5
We present measurements of H under pressure in MgB and in YNiBC. The changes in the shape of H are interpreted within current models and show the ev…

Enhancement of Critical Current across Single Grain Boundaries in YBa2Cu3Ox and Search for Superconductivity in Alkali Metals
T. Tomita, S. Deemyad, J. J. Hamlin +5
The ability of single grain boundaries in YBa2Cu3Ox bicrystalline rings to carry electrical current is found to be significantly enhanced under hydrostatic pressure. Nearly hydrost…
