Calculations of the superconducting properties of scandium under high pressure

In recent years the number of elements in the periodic table that become superconductors under pressure has increased to the point that this is no longer considered a rare phenomenon. Recent experiments suggest that scandium reaches a superconducting temperature of 9 K at a pressure of 74 GPa. Using the results of self-consistent band theory calculations, the McMillan theory, and the rigid-muffin-tin approximation, we have calculated the electron-phonon coupling and Tc for scandium, in good agreement with experiment. © 2007 U.S. Government.
