Neutron diffraction and nuclear quadrupole resonance (NQR) measurements wereemployed to investigate magnetic order in the non-ferroelectric phase precedingthe low-temperature multiferroic state in FeTe2O5Br. Refnement of the neutrondiffraction data and simulations of 79,81Br NQR spectra reveal that theincommensurate magnetic ordering in the non-ferroelectric state comprisesamplitude-modulated magnetic moments, similarly as in the multiferroic state.The two ordered states differ in the orientation of the magnetic moments andphase shifts between modulation waves. Surprisingly, all symmetry restrictionsfor the electric polarization are absent in both states. The differentferroelectric responses of the two states are thus argued to arise from thedifferences in the phase shifts between certain modulation waves, which cancelout in the non-ferrolectric state.
