摘要

The hydrostatic pressure effect on the newly discovered superconductor MgB2 has been determined. The transition temperature Tc was found to decrease linearly at a large rate of - 1.6 K/GPa, in good quantitative agreement with the ensuing calculated value of - 1.4 K/GPa within the BCS framework by Loa and Syassen, using the full-potential linearized augmented plane-wave method. The relative pressure coefficient d ln Tc/dp for MgB2 also falls between the known values for conventional sp and d superconductors. The observation, therefore, suggests that electron-phonon interactions play a significant role in the superconductivity of the compound.
