Abstract. The creation of solid-state refrigerating systems at cryogenic temperatures requires the development of magnetic field sources capable of holding strong magnetic fields for a long time without significant energy costs. High-temperature superconductors (HTS) The Y-Ba-Cu-O families in the form of bulk ceramics and tapes of film composites have the necessary properties 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. This paper presents the results of a comparative study of the process of capturing and retaining magnetic fields in the PSM of HTSP tape elements of two configurations: in the gap between two stacks of tape segments and in a cylindrical hole in a stack of tape segments. The experiments were carried out at temperatures from 3 to 90 K, in a magnetic field up to 10 T.
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.
