Superconductivity in a new layer compound of Ni$_{\mathrm{x}}$ZrTe$_{2}$

Since the discovery of superconductivity in chalcogenides in Fe-Se system and in iron pnictides much attention have been give for synthesis of new materials which can exhibit superconductivity. Within this context ZrTe$_{2}$ crystallizes in a CdI$_{2}$ prototype structure which posses van der Waals gap between Te bonding. In this work we will show that Ni intercalation between van der Waals gap induce superconductivity in this compound with superconducting critical temperature close to 8.0 K, which can vary with Ni content.
