Determination of the magnetic structure of TbCu2

Recently, we have discovered a long-range magnetic structure with a periodicity of 5.5 nm in TbCu2 with remarkable robustness against strain and size reduction . This long-range magnetic modulation was not present in the NdTbCu2 compound. In short, we believe that the series of RCu2 will be a phenomenal playground to explore the formation of the magnetic superstructures with the potential to pave the way for further studies.
We wish to perform single crystal diffraction in order to resolve the real magnetic structure of TbCu2.The Bragg peak appears at Q=0.1 Å-1, perfectly suited for SANS

近期，我们在TbCu₂中发现了一种周期为5.5 nm的长程磁结构，该结构对应变与尺寸缩减表现出优异的稳定性。这种长程磁调制现象并未在NdTbCu₂化合物中被观测到。综上，我们认为RCu₂系列化合物将成为探索磁超结构形成机制的绝佳研究平台，有望为后续相关研究奠定基础。
我们计划开展单晶衍射实验以解析TbCu₂的真实磁结构。其布拉格峰出现在Q=0.1 Å⁻¹处，完全匹配小角中子散射（Small Angle Neutron Scattering, SANS）的实验要求。
