Magnetization of superconducting rings by long-duration pulses

详细

After pulsed magnetization of the rings of high-temperature superconductors with a rectangular cross section, the magnitude of the trapped field has been measured depending on the decay time of the magnetization field. It has been shown that, by making use of the break of shielding current, one can magnetize the ring with a single pulse the rings to the maximum value corresponding to the field cooling process.
