The destructive magnets at ISSP can generate magnetic fields up to 1200 T, providing a unique opportunity to measure several physical properties of materials in magnetic field regions exceeding 100 T. The non-destructive magnets at ISSP have been used for various high precision measurements in magnetic fields up to 75 T. The following is a list of possible experiments in magnetic fields generated by each magnet. Before applying to a joint research project, please contact the person in charge of the experiment (written in the brackets below). If you are not sure who is in charge, please contact here.
