Query: Magnetic structure and spin wave excitations in the multiferroic
  magnetic metal-organic framework (CD$_3$)$_2$ND$_2$[Mn(DCO$_2$)$_3$]   We report the magnetic diffraction pattern and spin wave excitations in
(CD$_3$)$_2$ND$_2$[Mn(DCO$_2$)$_3$] 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-neighbour interactions along three directions of $J_1=-0.103(8)$~meV,
$J_2=-0.032(8)$~meV and $J_3=-0.035(8)$~meV.
