Unconventional superconductivity in weakly correlated, non-centrosymmetric $\mathrm{M}{\mathrm{o}}_3\mathrm{A}{\mathrm{l}}_2\mathrm{C}$

E. Bauer, G. Rogl, Xing-Qiu Chen +9

Electrical resistivity, specific heat and NMR measurements classify non-centrosymmetric $\mathrm{M}{\mathrm{o}}_3\mathrm{A}{\mathrm{l}}_2\mathrm{C}$ ($\beta$-Mn type, space group $P{4}_{1}32$) as a strong-coupled superconductor with…
