Abstract

Combined experimental and theoretical studies are reported of the Fermi surface, band structure, generalized magnetic susceptibility, electron‐phonon enhancement factor λ and superconducting transition temperature T_T of LaB₆. Whereas the unusually large λ values, ranging from 1.0 to 2.5, are expected to result in high T_T values, T_T is observed to be only 0.122°K. These results further emphasize the need for appropriate theoretical formulations for these systems.
