Abstract

The hexagonal-layered Ti₂InC compound is a member of the large family of lamellar materials that crystallize in the hexagonal structure with space group , which are isomorphs with the Cr₂AlC compound, and known as H-phase. In this work the Ti₂InC phase is investigated by X-ray diffraction, magnetization and resistivity measurements. Susceptibility and resistivity measurements display superconducting critical temperature close to 3.1 K. In spite of the great number of compounds which belong to this family, superconductivity has been reported only for four cases: Mo₂GaC, Nb₂SC, Nb₂AsC and Nb₂SnC. This work supports the existence of a new class of superconducting materials that crystallize in an H-phase.
