Abstract
Results of Raman measurements on RNi2B2C (R=Lu, Ho, Y) single crystals are reported. Raman peaks are observed at 190 cm-1 and near 830 cm-1. From the polarization-dependence measurements, these peaks are assigned to be the Ni-B1g and the B-A1g modes, respectively. Raman study on the effects of boron isotope 10B substitution for 11B in the LuNi2B2C crystals confirms that the mode near 830 cm-1 is due to the vibration of B atoms. However, from these single crystals, the expected Ni-Eg and B-Eg modes are not observed.
