Identifying the multiferroic phase of doped CuFeO_2 using inelastic neutron scattering

J. T. Haraldsen, F. Ye, R. S. Fishman +4

We report inelastic neutron scattering measurements that provide a distinct dynamical "fingerprint" for the multiferroic ground state of 3.5% Ga-doped CuFeO_2. The complex ground s…
