摘要

我们对线性磁电材料Mn3Ta2O8单晶样品进行了非弹性中子散射实验，该材料呈现共线反铁磁序，；在自旋哈密顿量的基础上，线性自旋波理论合理地再现了中子谱中观察到的许多模式，包括八个海森堡相互作用和一个易平面型单离子各向异性。在确定的自旋哈密顿量中发现了强烈的挫败感。

Spin dynamics in linear magnetoelectric material Mn₃Ta₂O₈.

We performed inelastic neutron scattering experiments on single crystal samples of a linear magnetoelectric material Mn₃Ta₂O₈, which exhibits a collinear antiferromagnetic order, to reveal the spin dynamics. Numerous modes observed in the neutron spectra were reasonably reproduced by linear spin-wave theory on the basis of the spin Hamiltonian including eight Heisenberg interactions and an easy-plane type single-ion anisotropy. The presence of strong frustration was found in the identified spin Hamiltonian.

期刊介绍： Journal of Physics: Condensed Matter covers the whole of condensed matter physics including soft condensed matter and nanostructures. Papers may report experimental, theoretical and simulation studies. Note that papers must contain fundamental condensed matter science: papers reporting methods of materials preparation or properties of materials without novel condensed matter content will not be accepted.
