Comprehensive vibrational studies on the multiferroic-to-normal-ferromagnetic crossover in isostructural Ni3−x Co x V2O8 (NCVO, x = 0–3.0) are performed using Raman scattering spectroscopy. The systematically red-shifted phonon modes are discussed in terms of the mode Grüneisen parameters, and are interpreted as a chemical pressure effect. In addition, we present evidence that the local symmetry is broken in the multiferroic phase.
