“…The crystal structure is found to be a variant of the layered ThCr 2 Si 2 structure with additional carbon atoms in the rare-earth plane. 3 Considerable excitement was generated by the discovery of superconductivity in a number of such compounds, 1,2,[4][5][6] with the highest T c of 23 K in YPd 5 B 3 C 0.3 , 5 and the interesting observation of interplay between superconductivity and magnetism in other systems. 8 Among the other members of this class, the mϭ2 and nϭ2 series has been synthesized for Tϭ Ni and Rϭ Lu and its crystal structure determined.…”

In the class of intermetallic compounds of general formula (RC͒ m (TB͒ n (Rϭ rare earth, Tϭ transition metal͒, superconductivity has been reported in several of the single RC layer (mϭ1 and nϭ2) compounds, but only in one two-layer (mϭ2, nϭ2) system ͓LuNi 1Ϫx ͑Cu/V͒ x BC͔. We report here the observation of superconductivity in a further two-layer compound YNi 1Ϫx Cu x BC with T c as high as 8.9 K. The corresponding LuNi 1Ϫx Cu x BC system shows an enhancement of T c up to 6.4 K upon Cu substitution. The principal structural effect of substitution in both systems is an expansion of the tetragonal lattice along the c axis.

“…By using rapid-quenching techniques, StroK m et al could also prepare ribbons out of YNi B C (39). A few compounds like ScNi B C (40) and ThNi B C (41a}41c) which also superconduct at 15 and 6 K respectively, were found to be metastable. In the¸nNi B C series of materials, it was found that Dy, Ho, Er, Tm, Lu, Y, Sc, and Th compounds exhibit superconductivity, out of which the magnetic rare earth analogues also exhibit magnetic transition.…”
