abstract = {Hyperfine interactions and Fe-specific lattice dynamics in
CuFeO2 were investigated by nuclear resonance scattering
methods and compared to ab initio lattice dynamics
calculations. Using nuclear forward scattering the collinear
spin structure at temperatures below about 11 K could be
confirmed, whereas the nuclear forward scattering results in
the intermediate temperature range between about 11 K and 14
K are incompatible with the assumption of a sinusoidal
distribution of spins parallel to the c axis of CuFeO2. The
critical behavior of the average hyperfine field at the
phase transition at about 14 K further supports a
three-dimensional model for the magnetism in this compound.
Moreover, using nuclear inelastic scattering by the 57Fe
Mössbauer resonance, Fe-specific lattice dynamics are found
to be strongly anisotropic with stiffer bonds in the ab
plane of the crystal. The powder averaged, Fe partial
density of phonon states can be well modeled using ab initio
calculations and low-energy phonons are found to deviate
from classical Debye-like behavior, indicating spin-phonon
coupling in this compound. Besides, the theoretical phonon
spectrum exhibits typical characteristics for
delafossite-type material.},
