Dynamic Spin-Lattice Coupling and Nematic Fluctuations in NaFeAs
We use inelastic neutron scattering to study acoustic phonons and spin excitations in single crystals of NaFeAs, a parent compound of iron-pnictide superconductors. NaFeAs exhibits a tetragonal-to-orthorhombic structural transition at T_{s}≈58 K and a collinear antiferromagnetic order at T_{N}≈45 ...
