Abstract
We investigate the effects of lattice distortions and anisotropy on the non-collinear ground state
and spin dynamics of the multiferroic phase of doped CuFeO2. Using a Holstein-Primakoff expansion,
we evaluate the change in the spin dynamics as lattice distortions and anisotropy distort the
simple incommensurate helix. Distinct features in the spin dynamics that are created by lattice
distortions and anisotropy have recently been observed in Ga-doped CuFeO2.
