The crystal structure of superconducting LuNi 2 B 2 C and the related phase LuNiBC
Summary
This article discusses the crystal structure of two new phases found in the Lu–Ni–B–C system: LuNi 2 B 2 C and LuNiBC. LuNi 2 B 2 C is a superconductor with a transition temperature of 16.6 K, and LuNiBC is a closely related, non-superconducting phase. The superconductor is a variant on the layered ThCr 2 Si 2 -type structure, while LuNiBC is derived from LuNi 2 B 2 C by adding a layer of Lu–C, creating a NaCl-type intergrowth. The article suggests that a new homologous series of intermetallic phases could be derived from these two structures.
