We report the magnetic diffraction pattern and spin-wave excitations in ${(\mathrm{CD}}_3{)}_2{\mathrm{ND}}_2{\left[{\mathrm{Mn}(\mathrm{DCO}}_2\right)}_3]$ 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 $J_1=-0.103\left(8\right)$ meV, $J_2=-0.032\left(8\right)$ meV, and $J_3=-0.035\left(8\right)$ meV.

多铁磁性金属-有机骨架（CD3）2ND2 [Mn（DCO2）3]中的磁性结构和自旋波激发

我们报告了磁衍射图和自旋波激发 ${（\mathrm{光盘}}_3{）}_{\mathrm{2个}}{\mathrm{ND}}_{\mathrm{2个}}{[{锰（\mathrm{DCO}}_{\mathrm{2个}}）}_3]$使用弹性和非弹性中子散射进行测量。磁性结构显示为$G$型磁铁，其磁矩指向 $b$轴。通过与基于线性自旋波理论的模拟进行比较，我们为这种多铁性金属-有机骨架材料中的磁性相互作用建立了一个模型。这些相互作用形成了一个三维网络，沿着三个方向具有反铁磁最近邻相互作用。${Ĵ}_{\mathrm{1个}}=-0.103（8）$ MV ${Ĵ}_{\mathrm{2个}}=-0.032（8）$ meV，和 ${Ĵ}_3=-0.035（8）$ meV。
