“…Indeed, even small deviations of both C and B content yield disappearance of the superconducting properties [116]. Similarly, it was observed, that superconductivity in DyNi 2 [B 2 C] is very sensitive to deviations from the integral Dy content [211].…”

“…The same might hold true for all discussed borocarbides, since dependencies of physical properties on thermal history of the samples was frequently discussed [61][62][63][112][113][114][115]. For example, some unit cell parameter dependences on B and C contents in HoNi 2 [B 2 C] in agreement with further investigation techniques demonstrate an at least small homogeneity range within these two constituents with deviations from ideal composition leading to disappearance of superconductivity [116]. On annealing superconductivity appears, but with a significantly lower T c than the value for well crystallized bulk material.…”

Abstract. Few years after the discovery of superconductivity in high-T c cuprates, borocarbides and shortly after nitridoborates with reasonably high T c s up to about 23 K attracted considerable attention. Particularly for the rareearth metal series with composition RNi 2 [B 2 C] it turned out, that several members exhibit superconductivity next to magnetic order with both T c above or below the magnetic ordering temperature. Therefore, these compounds have been regarded as ideal materials to study the interplay and coexistence of superconductivity and long range magnetic order, due to their comparably high ordering temperatures and similar magnetic and superconducting condensation energies. This review gathers information on the series
