An effect of slowing down of lift force relaxation in a superconducting levitation system was studied. The relaxation dependences for the interaction force between a high-temperature superconductor and a permanent magnet, when a levitating object was

The effect of an external nonuniform magnetic field on the flux creep rate in a high-temperature superconductor with trapped magnetic flux was studied. The magnetic relaxation was suppressed when the superconductor was put into a field of permanent m

The creep of a magnetic flux trapped in a bulk high-temperature superconductor has been studied. It has been found that the magnetic relaxation is retarded when the superconductor is placed near a ferromagnet. The value of the retardation effect depe

This study deals with the decrease in the levitation force under the action of an ac field up to the frequency at which oscillations of the superconducting suspension are limited by inertia. The lifting force was measured as a function of the ac fiel

The effect of the magnetic flux creep on the levitation stability of high-temperature superconductors was studied. It was shown experimentally that under a unipolar magnetization the levitation force decreased at a logarithmic velocity characteristic

The phenomenon of the suppression of magnetic relaxation in a high-temperature superconductor (HTSC) with trapped magnetic flux has been observed when the superconducting sample approached a ferromagnet. It is suggested that the ferromagnet is magnet

The phenomenon of the magnetic relaxation slowing down in levitated superconductors has been observed. It is suggested that the decrease in the magnetic relaxation rate is related to a magnetic bias feedback in the sample, which restores a nonequilib

Experimental and calculated dependences of granular superconductor magnetic susceptibility on the superconducting volume fraction in regimes of shielding (ZFC), Meissner effect (FC) and remanence (REM) were determined. Fractional dependences were cal
