抜粋

The temperature rise during the field cooling (FC) magnetizing process with various sweep rates by using a 10 T superconducting solenoid magnet was systematically evaluated with respect to an YBCO single domain trapped-field magnet cooled to 57-75 K by a GM refrigerator. The maximum temperature change has reached 6 K when the sweep rate was -11.3 mT/s and initial temperature of 57 K. The recent elevation of the sweep rate of superconducting magnet and the critical current density of bulk samples have made the heat generation serious even in the FC operation by quasi-static magnetic field.
