Low-energy phonons in TbNi2B2C and HoNi2B2C

We report inelastic neutron-scattering experiments on RNi2B2C single crystals (R=Tb and Ho) to investigate the dispersion of low-energy phonons. Both compounds order antiferromagnetically at low temperatures. For superconducting HoNi2B2C we observe a strong softening of two phonon branches similar t...
