论文摘要
单晶体弹性和非弹性中子散射实验在高磁场的沮丧的铁 - 抗铁磁铁SRZNVO（PO4）2上进行。仅研究了完全极化的状态，天前阶段和柱状抗铁磁阶段，仅研究了天前阶段。观察到的自旋波带宽的重新归一化，在磁化曲线中不同分支和非线性之间的强度的重新分布都表明与经典旋转波理论有强偏差。先前观察到的预饱和度转变归因于dzyaloshinskii-Moriya相互作用的交错模式。
Single crystal elastic and inelastic neutron scattering experiments are performed on the frustrated ferro-antiferromagnet SrZnVO(PO4)2 in high magnetic fields. The fully polarized state, the presaturation phase and the columnar-antiferromagnetic phase just bellow the presaturation phase were investigated. The observed renormalization of spin wave bandwidths, re-distribution of intensities between different branches and non-linearities in the magnetization curve are all indicative of strong deviations from classical spin wave theory. The previously observed presaturation transition is attributed to a staggered pattern of Dzyaloshinskii-Moriya interactions.
