Abstract :
In this work the Ti2InN phase is investigated by X-ray diffraction, magnetic and resistivity measurements. X-ray powder patterns suggest that all peaks can be indexed with the hexagonal phase of Cr2AlC prototype. Electrical resistance as a function of temperature reveals superconductivity below 7.3 K. M ( H ) hysteresis loops show typical type-II superconductivity. Using R ( H ) versus T measurements we estimated μ o H c 2 ( 0 ) ∼ 10.8 T and ξ ( 0 ) ∼ 55.2 Å . The results show unambiguously that Ti2InN is the first nitride superconductor belonging to the Mn+1AXn family.
