Spin Excitation in Coupled Honeycomb Lattice Ni${}_2$InSbO${}_6$

Abstract

We performed an inelastic neutron scattering experiment on a polycrystalline sample of a helimagnet Ni${}_2$InSbO${}_6$ to construct the spin Hamiltonian. Well-defined spin-wave excitation with a band energy of 20 meV was observed below $T_N=76$ K. Using the linear spin-wave theory, the spectrum was reasonably reproduced with honeycomb spin layers coupled along the stacking axis (the $c$ axis). The proposed spin model reproduces the soliton lattice induced by a magnetic field applied perpendicular to the $c$ axis.
