Abstract

The spin-flop phase of a honeycomb antiferromagnet of Mn_0.84Mg_0.16TiO₃ has been studied under magnetic field along normal direction to the honeycomb plane by neutron scattering. With increasing a magnetic field from 0 to 5 T, the inelastic scattering intensity increased by 1.5 times at (1 0 0), where the magnetic structure was found to be collinear-antiferromagnet with the spin parallel to [1 1 0] direction. The spin direction is consistent with a 1.5 times increase of the inelastic intensity. The negligible energy difference between K and KA points suggests small values for both Dzyaloshinskii-Moriya interaction and bond-dependent symmetric anisotropic exchange interaction in this material.
