The paper reviews recent progress in field cycling (FC) NMR instrumentation and its application to solid state physics. Special emphasis is put on our own work during the last 15years on instrumentation, theory and applications. As far as instrumentation is concerned we report on our development of two types of electronical FC relaxometers, a mechanical FC relaxometer and a combination of FC and one-dimensional microimaging. Progress has been achieved with respect to several parameters such as the accessible field and temperature range as well as the incorporation of sample spinning. Since an appropriate analysis of FC data requires a careful consideration of relaxation theory, we include a theory section discussing the most relevant aspects of relaxation in solids which are related to residual dipolar and quadrupolar interactions. The most important limitations of relaxation theory are also discussed. With improved instrumentation and with the help of relaxation theory we get access to interesting new applications such as ionic motion in solid electrolytes, structure determination in molecular crystals, ultraslow polymer dynamics and rotational resonance phenomena.

固态场循环核磁共振弛豫：仪器改进和新应用

该论文回顾了场循环 (FC) NMR 仪器的最新进展及其在固态物理学中的应用。在过去的 15 年中，我们特别强调了我们自己在仪器、理论和应用方面的工作。就仪器而言，我们报告了我们开发的两种电子 FC 弛豫计、机械 FC 弛豫计以及 FC 和一维显微成像的组合。在几个参数方面已经取得了进展，例如可接近的场和温度范围以及样品旋转的结合。由于对 FC 数据的适当分析需要仔细考虑松弛理论，因此我们包括一个理论部分，讨论与残余偶极和四极相互作用相关的固体松弛的最相关方面。还讨论了松弛理论最重要的局限性。借助改进的仪器和弛豫理论，我们可以获得有趣的新应用，例如固体电解质中的离子运动、分子晶体中的结构测定、超慢聚合物动力学和旋转共振现象。
