Abstract

Pressure-dependent transport measurements of Ir_1\ensuremath-xPt_xTe₂ are reported. With increasing pressure, the structural phase transition at high temperatures is enhanced while its superconducting transition at low temperatures is suppressed. These pressure effects make Ir_1\ensuremath-xPt_xTe₂ distinct from other studied TX₂ systems exhibiting a charge density wave (CDW) state, in which pressure usually suppresses the CDW state and enhances the superconducting state. The results reveal that the emergence of superconductivity competes with the stabilization of the low-temperature monoclinic phase in Ir_1\ensuremath-xPt_xTe₂.
