Superconductivity was already detected in 18 Heusler alloys, i.e. ternary intermetallics forming a large class of cubic compounds having the composition TX₂Z, where T and X are transition and noble metal atom and Z is sp element. In the paper we present the results of resistivity, dc and ac susceptibility measurements of polycrystalline ZrNi₂In. Critical temperature of the compound (defined as the onset of magnetic transition) was equal to T_c = 9 K, surprisingly high for this class of compounds (the maximum value of critical temperature was previously obtained for YPd₂Sn and was equal to T_c = 4.64 K).
From the dc magnetization measurements lower and upper critical fields were evaluated and their temperature dependence was obtained. From th slope of dHc₂/dT superconducting parameters of the material were calculated from WHH theory.
