Abstract

Two-dimensional (2D) correlation analysis is applied to the temperature dependence on the Raman spectra of superconducting YNi₂B₂C single crystal. 2D correlation analysis on the temperature dependence of the B_1g superconducting gap peak shows strong correlation with the Ni B_1g phonon peak near 200 cm^-1. The analysis on the B _1g phonon peak itself shows that the peak is composed of essentially two peaks at 197 and 203 cm^-1, and only the weight of the two peaks changes as the temperature changes. The result suggests that there are two distinctive environments of the Ni-B bonds in YNi₂B₂C system at the superconducting state.
