Enhanced $T_c$ and multiband superconductivity in the fully-gapped ReBe${}_{22}$ superconductor

T. Shang, A. Amon, D. Kasinathan +8

In search of the origin of superconductivity in diluted rhenium superconductors and their significantly enhanced $T_c$ compared to pure Be (0.026 K), we investigated the intermetal…
