Rev. B 48, 15574 (1993)]. We find that compressed, bcc yttrium has a large electron-phonon coupling with lambda=1.8, leading to a superconducting transition temperature T_c ~ 30 K or above. Our results indicate that the large electron-phonon coupling is due to the lattice hardening.Added linear-response done using full-potential, LMTO methodSuperconductivityMaterials Sciencetext
