Abstract | IrTe2, a layered compound with a triangular iridium lattice, exhibits a structural phase transition at approximately 250 K. This transition is characterized by the formation of Ir-Ir bonds along the b-axis. We found that the breaking of Ir-Ir bonds that occurs in Ir1-xPtxTe2 results in the appearance of a structural critical point in the T = 0 limit at x(c) similar or equal to 0.035. Although both IrTe2 and PtTe2 are paramagnetic metals, superconductivity at T-c = 3.1 K is induced by the bond breaking in a narrow range of x >= x(c) in Ir1-xPtxTe2. This result indicates that structural fluctuations can be involved in the emergence of superconductivity.
