摘要：

In this work the Nb2InC phase is investigated by X-ray diffraction, heat capacity, magnetic and resistivity measurements. Polycrystalline samples with Nb2InC nominal compositions were prepared by solid state reaction. X-ray powder patterns suggest that all peaks can be indexed with the hexagonal phase of Cr(2)AIC prototype. The electrical resistance as a function of temperature for Nb(2)Inc shows superconducting behavior below 7.5 K. The M(H) data show typical type-II superconductivity with H-c1 similar to 90 Oe at 1.8 K. The specific heat data are consistent with bulk superconductivity. The Sommerfeld constant is estimated as gamma similar to 12.6 mJ mol(-1) K-1. (C) 2009 Elsevier B.V. All rights reserved.
