Abstract
In recent years of studies in “unconventional” superconductivity, researchers have concentrated on exotic behavior of the heavy fermion and cuprate superconductors. However, even superconductors that are thought to be conventional BCS-type show signs of exotic properties. The borocarbides with the generic formula RNi2B2C (R = Y, rare earths) have shown especially rich physics. [1] Recently, we have observed finite scattering amplitude below the superconducting gap of LuNi2B2C and YNi2B2C using electronic Raman spectroscopy. Understanding the physics in borocarbides might help us unify present knowledge of superconductivity in general. In this article, we further address the peculiar behavior of the 2Δ peak and the sub-gap features, reported in our earlier electronic Raman measurements[2].
