Abstract
We report the magnetic diffraction pattern and spin-wave excitations in (CD3)2ND2[Mn(DCO2)3] measured using elastic and inelastic neutron scattering. The magnetic structure is shown to be a G-type antiferromagnet with moments pointing along the b axis. By comparison with simulations based on linear spin-wave theory, we have developed a model for the magnetic interactions in this multiferroic metal-organic framework material. The interactions form a three-dimensional network with antiferromagnetic nearest-neighbor interactions along three directions of J1 = −0.103(8) meV, J2 = −0.032(8) meV, and J3 = −0.035(8) meV.
