Research on Fabrication Method of Low-Temperature Superconducting Joints

Superconducting joints (SJs) are essential materials for the development of modern technology, which is widely used in Nuclear Magnetic Resonance (NMR), Magnetic Resonance Imaging (MRI), and other fields. This paper introduces the preparation method of the low-temperature SJs, compares their characteristics and advantages, and introduces the measurement method of small resistance and the most important application of SJs.
