The main objective of this proposal is to design, fabricate and improve self-assembled rolled-up microcoils for solid state magnetic resonance experiments, especially for low temperature experiments. With these microcoils, we want to study intrinsic static and dynamic properties of quantum spin systems by NMR, for which the conventional NMR experiments are limited due to their smaller sample size or the unavailability of single crystal samples. In particular, the proposed project aims to investigate samples exhibiting low dimensional magnetism or unconventional superconductivity. Immediate materials under consideration include tiny F-doped LaFeAsO single crystals, microcrystals of LiCuSbO4 and BiCoPO5, and exfoliated microcrystals of 2D van der Waals materials such as TM2P2S6, TM = Ni, Mn, Fe, etc. The objective of this proposal is not to study all of these materials in detail, but to find a suitable candidate and proof the applicability of rolled-up microcoils for solid state NMR.

该方案的主要目的是设计、制造和改进用于固态磁共振实验，特别是低温实验的自组装卷起微线圈。利用这些微线圈，我们希望通过核磁共振来研究量子自旋系统的本征静态和动态性质，但由于样品较小或无法获得单晶样品，传统的核磁共振实验受到了限制。特别是，拟议的项目旨在调查表现出低维磁性或非传统超导电性的样品。目前正在考虑的材料包括微小的F掺杂LaFeAsO单晶，LiCuSbO4和BiCoPO5微晶，以及2D van der Waals材料的剥离微晶，如TM2P2S6，Tm=Ni，Mn，Fe等。这项建议的目的不是详细研究所有这些材料，而是找到合适的候选材料，并证明卷起的微线圈在固态核磁共振中的适用性。
