Comment on "Temperature dependence of the Raman-active B_{1g} and A_{1g} modes in YNi_2B_2C"
Abstract
Description
Both principal conclusions of Hirata and Takeya paper (Phys. Rev. B 57, 2671 (1998)) dealing with an analysis of the electron-phonon coupling strengths and stating the existence of two boron-related fully symmetric phonon modes in YNi_2B_2C are argued not to be supported by experimental data and not justified.
