Re*

With T_c ∼9.6 K, Be₂₂Re exhibits one of the highest critical temperatures among Be-rich compounds. We have carried out a series of high pressure electrical resistivity measurements to 30 GPa. The data show that the critical temperature T_c is suppressed gradually at a rate of dT_c/dP = –0.05 K/GPa. Density functional theory calculations demonstrate a corresponding increase in the density of states at the Fermi level. Together, these results indicate that the electron-phonon coupling decreases with pressure. We discuss the relationship between low-Z Be-rich superconductors and the high-Tc superhydrides.
