dc.description.resumoThe anisotropic easy-plane Heisenberg antiferromagnet with spin one and a Moriya-Dzyaloshinskii term is studied in the disordered phase of the honeycomb lattice, at zero temperature, using a boson approach. We analyze the effect of the Moriya-Dzyaloshinskii term in the phase diagram. This term breaks the time reversal symmetry of the lattice and opens a gap in the dispersion relation. The opening of the gap could lead to nontrivial topological effects. The dispersion relations are shown for some values of the parameters.pt_BR
