Abstract

Mineral calaverite AuTe2 is a layered compound with an incommensurately modulated structure. The modulation is characterized by the formation of molecular-like Te2 dimers. We have found that the breaking of Te2 dimers that occurs in Au1-xPt xTe2 results in the emergence of superconductivity at Tc = 4:0 K.
