Abstract. Composite tapes based on high-temperature superconductor (HTSC) films of the Y-Ba-Cu-O family can be used to create permanent superconducting magnets (PSM) that capture and maintain a constant magnetic field for a long time at temperatures of 90 K and below. In this paper, an original PSM design in the solenoid configuration consisting of rings of HTSC tapes is proposed. The results of a study of the process of capturing and holding magnetic fields in the solenoid are presented, including the dependence of the magnetic field in the solenoid center on the temperature after switching off the external field source, followed by cooling the PSM in the field. The stability of the held field in the PSM at a constant temperature is also considered. The experiments were carried out at temperatures from 3 to 100 K, in a magnetic field of up to 6.4 T. The possibility of using solenoids based on HTSC tapes for applications in promising solid-state cooling systems based on the magnetocaloric effect is discussed.

Key words: permanent magnets, high-temperature superconductors, magnetocaloric effect, magnetic solid-state cooling at cryogenic temperatures, magnetic flux capture.

Financing: The study was supported by the Russian Science Foundation, grant No. 20-19-00745-P, https://rscf.ru/project/20-19-00745/
