Field-induced magnetic incommensurability in multiferroic Ni3TeO6
Abstract
Using single-crystal neutron diffraction we show that the magnetic structure Ni<sub>3</sub>TeO<sub>6 </sub>at fields above 8.6 T along the <i>c</i><b> </b>axis and low temperature changes from a commensurate collinear antiferromagnetic structure with spins along <i>c</i> and ordering vector <i>Q</i><sub>C</sub>=(001.5) to a conical spiral with propagation vector <i>Q</i><sub>IC</sub>=(001.5±<i>δ</i>), <i>δ</i>∼0.18, having a significant spin component in the (<i>a</i>,<i>b</i>) plane. We determine the phase diagram of this material in magnetic fields up to 10.5 T along <i>c</i> and show the phase transition between the low field and conical spiral phases is of first order by observing a discontinuous jump of the ordering vector. <i>Q</i><sub>IC</sub> is found to drift both as a function of magnetic field and temperature. Preliminary inelastic neutron-scattering data reveal that the spin-wave gap in zero field has minima exactly at <i>Q</i><sub>IC</sub> and a gap of about 1.1 meV consisting with a crossover around 8.6 T. Further, a simple magnetic Hamiltonian accounting in broad terms for these is presented. Our findings confirm the exclusion of the inverse Dzyaloshinskii-Moriya interaction as a cause for the giant magnetoelectric due to symmetry arguments. In its place we advocate for the symmetric exchange striction as the origin of this effect.
