Abstract
The new class of rare-earth transition-metal borocarbides with the general formula RNi2B2C attracted the interest of many scientists, because of their wide variety of physical properties: Compounds with R = Y and Lu exhibit fairly high superconducting transition temperatures, T c , of about 15—16 K [1]; magnetism coexists with superconductivity for R = Dy, Ho, Er and Tm [2] whereas only antiferromagnetic order occurs for R = Pr, Nd, Sm, Gd and Tb [3]. The Néel temperatures, T N , axe, of the same order of magnitude as T c and scale for both the light- and heavy rare-earth borocarbides approximately with the de Gennes factor, (gJ—1)2 J(J+1), which is to a first approximation also the case for the depression of superconductivity for the magnetic heavy rare-earth borocarbide superconductors. For a review on superconductivity and magnetism in quaternary borocarbides and boronitrides see e.g. [4].
