Solenoid from experimental HTS tape for magnetic refrigeration
E. P. Krasnoperov, V. V. Guryev, S. V. Shavkin +5
The project of superconducting magnetic system (SMS) for the magnetic refrigerator machine is proposed. The second-generation high-temperature superconducting tapes for SMS are dev…
The break of shielding current at pulsed field magnetization of superconducting annuli
V. S. Korotkov, E. P. Krasnoperov, A. A. Kartamyshev
The superconducting current breaking effect at pulsed field magnetization of HTS annuli was carefully investigated. It is proposed the simple model for qualitative description of t…
Flux jumps at pulsed field magnetization
V. S. Korotkov, E. P. Krasnoperov, A. A. Kartamyshev
Flux jumps lead to 10-20 times reduction of the shielding currents at a pulsed field magnetization of a melt-grown HTS annuli. The induced circular currents and the related trapped…
Negative magnetic relaxation in superconductors
E. P. Krasnoperov
It was observed that the trapped magnetic moment of HTS tablets or annuli increases in time (negative relaxation) if they are not completely magnetized by a pulsed magnetic field.…
The hybrid magnet with a logarithmic in time field deviation
E. P. Krasnoperov, A. A. Kartamyshev, D. I. Puzanov +2
The pulsed-field magnetization of hybrid magnet (soft ferromagnetic and melt-grown superconductor Y-Ba-Cu-O) was investigated at T = 78K. It is shown that choosing the pulse amplit…
Magnetic relaxation in pulse-magnetized high-temperature superconductors
A. A. Kartamyshev, E. P. Krasnoperov, Yu. D Kuroedov +2
A magnetic field relaxation at the center of a pulse-magnetized single-domain Y-Ba-Cu-O superconductor at 78K has been studied. In case of a weak magnetization, the magnetic flux d…
