摘　　要：核磁共振作为一种重要的谱学研究手段,在高温超导体的机理研究中发挥了极其重要的作用.近年来,随着新型铁基高温超导材料家族的发现以及基于强磁场下核磁共振技术的发展,相关高温超导方面的核磁共振研究也有了许多新的进展,这些工作对高温超导电性的机理研究起到了积极的推动作用.本文将就核磁共振技术在铜氧化物高温超导体和铁基高温超导体这两大类高温超导材料中的若干最新研究进展进行一个有针对性的概述和梳理,希望对后续高温超导电性的机理研究以及材料探索能起到一些启示作用.As an important spectroscopy research technique,nuclear magnetic resonance(NMR)has played an important role in exploring the mechanism of high-temperature superconducting pairing.In the past decade,due to the discovery of ironbased high-temperature superconductors and the development of high magnetic field NMR technology,NMR studies on high-temperature superconductivity have made great progress,which has strongly promoted the research on the pairing mechanism.In this review,we will give an overview of the latest research progress of NMR studies on two hightemperature superconducting families,copper-oxide high-temperature superconductors and iron-based high-temperature superconductors.We hope this can provide some insights and stimulate more theoretical and experimental researches on understanding the high-Tc superconductors.
