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