Abstract
- We report the discovery of bulk superconductivity in Sc<subscript>6</subscript>MTe<subscript>2</subscript> with seven kinds of transition-metal elements M. The critical temperatures for M = 3d elements are higher than those for 4d and 5d elements and increase in the order of M = Ni, Co, and Fe with the highest Tc of 4.7K in Sc<subscript>6</subscript>FeTe<subscript>2</subscript>. First principles calculations indicate the presence of significant contribution of Fe 3d orbitals at the Fermi energy, which most likely enhance the Tc of Sc<subscript>6</subscript>FeTe<subscript>2</subscript>. The upper critical field for M = Os is considerably enhanced by the strong spin-orbit coupling. These results show Sc<subscript>6</subscript>MTe<subscript>2</subscript> to constitute a unique family of d-electron superconductors, in which d electrons of 3d and 5d M atoms strongly influence the superconducting properties.
