✦ Synopsis

Li and Sc are two of the 23 elements which only superconduct under high pressure. In previous studies T c for Li reaches 14 K at 30 GPa, but for Sc only 0.35 K at 21 GPa. We determined T c ðPÞ for Sc to be 74.2 GPa and found that T c increases monotonically with pressure to 8.2 K. Changes in the superconducting phase diagram of monovalent Li are studied upon alloying with 10% divalent Mg.
