Abstract
Copyright (c) 1997 Elsevier Science S.A. All rights reserved. Quaternary borocarbide superconductors RENi2B2C (RE=Y, Dy, Ho, Er, Tm and Lu) have several features which make them ideal candidates to study one of the most exciting and intriguing phenomena of condensed matter, viz., the interplay of superconductivity and long range magnetic order. Not only their superconducting transition temperatures are the highest among the intermetallic superconductors, their magnetic ordering temperatures are also the highest among all the known magnetic superconductors. DyNi2B2C presents a very interesting situation; superconductivity sets in an already magnetically ordered lattice. Other examples of this interplay in the borocarbide family will be presented. Absence of superconductivity in YbNi2B2C is rather anomalous; it points to the 4f-conduction electron hybridization.
