摘要

Two new quaternary borocarbide phases were discovered in the Y-Ru-B-C system: the (1111) YRuBC phase of the LuNiBC-type structure with tetragonal lattice parameters a =3.625-3.630 Å and c=7.775-7.874 Å, and the (1221) YRu2B2C phase of the LuNi2B 2C-type structure with tetragonal lattice parameters a=3.742-3.787 Å and c=10.278-10.453 Å. Bulk superconductivity of 9.7 K was observed from transport and magnetic measurements for the annealed YRu 2B2C sample with a short Ru-Ru bond length d(Ru-Ru) = √2 a/2=2.646 Å.
