Abstract
We report here our discovery of bulk superconductivity at rather high Tc in samples having nominal compositions YNi4BO0.2 (Tc≊12.5 K) and YNi2B3O0.2 (Tc≊13.5 K). While YNi4BC0.2 seems to be a single phase material, YNi2B3C0.2 is a multiphase system. Our experimental results show that the two materials are distinct superconductors. Discovery of superconductivity in these materials is of significance since not only is their Tc high (>10 K) but they also have nickel in large proportions. No nickel-based ternary superconductor was previously known.
