Abstract

Abstract Significant scientific breakthroughs often arise from research conducted under extreme conditions, such as ultrahigh magnetic fields. Ultrahigh field nuclear magnetic resonance (NMR) provides a cutting-edge platform for studying material properties under extreme conditions. However, pursuing ultrahigh NMR presents considerable challenges, with only a few institutions worldwide having the requisite technical capabilities. After several years of research and development, we have successfully created the world’s first high-temperature superconducting (HTS) NMR experimental instrument under low-temperature measurement with a field strength exceeding 25 T using the Bi-2223 HTS double-pancake winding technique. The instrument has demonstrated exceptional performance, and stable operation, fully satisfying the demands of the user facility. The open operation of this experimental facility will significantly support basic scientific research in China and around the world.
