Abstract
Berry's topological phase acquired during adiabatic evolution of systems is considered for transverse acoustic phonons in a helically wound rod of ferromagnetic material. Berry's phase is calculated in the presence of magnon-phonon interaction and small deviation from cubic symmetry. A simple dependence of the phase on these perturbations is found, indicating that the presence of the magnon-phonon interaction is important to stabilize the phase against the destructive effect of the velocity-difference between two Iinearly-polarized transverse phonons. This dependence could be detected by measuring intensities of linearly-polarized waves with changing winding number of the helix.
