Self-Assembled Rolled-Up Microcoils for Solid-State Nuclear Magnetic Resonance Spectroscopy

本课题的主要目的是设计、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固有静态和动态特性，而传统的核磁共振实验由于其较小的样本量或无法获得单晶样品而受到限制。特别地，拟议的项目旨在研究具有低维磁性或非常规超导性的样品。直接考虑的材料包括微小的掺f的LaFeAsO单晶，LiCuSbO4和BiCoPO5的微晶，以及二维范德华材料的脱落微晶，如TM2P2S6， TM = Ni, Mn， Fe等。本提案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状微线圈对固态核磁共振的适用性。

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.
