Capture of magnetic flux in high-temperature superconductor YBa$_2$Cu$_3$O$_7$ and its destruction

A creation of new-generation solid-state cryogenic systems requires the development of sources of high magnetic fields exceeding permanent magnets in the strength. In this work, the process of capturing a magnetic field up to 10 T by the high-temperature superconductor YBa$_2$Cu$_3$O$_7$ is experimentally investigated. The dependences of the magnetic flux captured in the superconductor on temperature are obtained.
