## Description

- description: Superconducting magnets used in applications such as magnetic resonance
    imaging (MRI) and nuclear magnetic resonance (NMR) require significant temporal
    magnetic field stability, which can be achieved when the MRI and NMR magnets are
    operated in the persistent current mode (persistent-mode) using superconducting
    joints. However, the ultra-high field MRI and NMR magnets are sometimes operated
    in the driven mode. Herein, we present an analysis of the temporal magnetic field
    drift and fluctuations observed for MRI and NMR magnets operating in the driven
    mode and an exploration of effective methods for stabilizing the temporal magnetic
    field fluctuations. In the last decade, substantial improvements have been achieved
    in superconducting joints between high-temperature superconductors (HTSs). These
    superconducting joints enable the development of persistent-mode ultra-high field
    magnets using HTS coils. Therefore, we herein review the superconducting joint
    technology for HTS conductors and describe the results of the persistent-mode
    operation achieved by a medium-field NMR magnet using an HTS coil. Particularly,
    the cutting-edge progress achieved concerning HTS superconducting joints, including
    joining methods, superconducting properties, and future prospects, is highlighted
    along with the issues that need to be addressed.
