dc.description.abstractThe phonons in rare earth nickel borocarbides are investigated using an angular force model approach. The analytical expressions for the Raman and the infrared frequencies of these compounds have been determined for the first time. A comparison of the expressions of the Raman modes with the expression of the similar modes in Nd Ce CuO has been made and the correspondence discussed. It has been observed that the angular forces between Lu and C atoms in Lu–C layer are the most important factor in obtaining a good agreement for the phonons with the experimentally measured inelastic neutron scattering results in the case of LuNi2B2C.en
