论文摘要
我们在零磁场上介绍了Shastry-Sutherland晶格系统TBB $ _4 $的单晶中子衍射研究，并在沿晶体学$ C $轴上应用的高达35 t的脉冲高磁场下。虽然我们的结果证实了零场的磁性结构以及半磁化高原的磁性结构，但它们为$ \ frac {2} {9} $ - 和$ \ frac {1} {1} {3} $ - 在该系统中观察到了磁化固醇。极化的4旋式平面的条纹模型与中子衍射数据完全一致，其条带密度与宏观磁化相对增加。存在同样适合的替代模型，这些模型解释了观察到的Bragg峰，这些峰在脉冲高磁场实验中固有地受到限制。我们讨论了$ Q $空间中的不同强度分布，该分布可用于在未来的实验中区分这些模型。
We present a single-crystal neutron diffraction study on the Shastry-Sutherland lattice system TbB$_4$ at zero magnetic field and under pulsed high magnetic fields up to 35 T applied along the crystallographic $c$ axis. While our results confirm the magnetic structures at zero-field as well as those at the half- and full-magnetization plateaus, they offer new insight into the $\frac{2}{9}$- and $\frac{1}{3}$-magnetization plateaus observed in this system. A stripe model of polarized 4-spin-plaquettes whose stripe density proportionally increases with the macroscopic magnetization is in full agreement with the neutron diffraction data. Equally well suited alternative models exist which explain the observed Bragg peaks which are inherently limited in a pulsed high magnetic field experiment. We discuss the different intensity distribution in $Q$ space which can be used to distinguish these models in future experiments.
