Abstract

Superconducting bulk properties of ternary Nb2 BN are confirmed and are described by means of magnetization, electronic transport and specific-heat measurements. BCS conventional super- conductivity is found with Tc = 4.4 K. Critical fields Hc1 (0)= 93 Oe and Hc2 (0)= 2082 Oe are extrapolated by magnetic and resistivity measurements. The specific heat data reveals {\gamma} = 6.3 mJ/mol K2 and {\beta} = 0.293 mJ/mol K4 in good agreement with the BCS Theory.
