- Abstract
- Results of Raman measurements on R Ni 2 B 2 C (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- B 1 g and the B- A 1 g modes, respectively. Raman study on the effects of boron isotope 10 B substitution for 11 B in the LuNi 2 B 2 C 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- E g and B- E g modes are not observed. © 1996 The American Physical Society.
