Large Ca Isotope Effect in CaC6
D. G. Hinks, D. Rosenmann, H. Claus +2
We have measured the Ca isotope effect in the newly discovered superconductor CaC6. The isotope effect coefficient is 0.50(7). If one assumes that this material is a conventional e…

The Dependence of Tc on Hydrostatic Pressure in Superconducting MgB2
T. Tomita, J. J. Hamlin, J. S. Schilling +2
The dependence of Tc on hydrostatic (He-gas) pressure has been determined to 0.7 GPa. We find that Tc decreases linearly and reversibly under pressure at the rate dTc/dP = -1.11 +-…
