It was shown experimentally that under a unipolar magnetization the levitation force decreased at a logarithmic velocity characteristic of the creep process. If the current structure was bi- or multi-polar one, which was formed in a sample exposed to a reversing external magnetic field, the force remained unchanged during a certain period of time. The theory of relaxation of magnetization and force for a partial and full penetration of the critical state was considered. It was shown that relaxation decelerated sharply if the region with a current producing the main magnetization was far from the superconductor surface. A concept of an open and internal magnetic relaxation was introduced. The time of the internal relaxation for different reverse depths was estimated. The calculated values approached the experimental values of the levitation stabilization time |

Boltachev // AIP Conference Proceedinds "Nucleation and atmospheric aerosols 2000" : 15th International Conference. - Rolla, Missouri (USA), 2000. - Vol. 534. - С. 420 Рубрики: ФИЗИКА Кл.слова (ненормированные): NUCLEATIONS -- HOMOGENEOUS NUCLEATION -- CRYOGENICS Аннотация: Nucleation in binary solutions of cryogenic liquids has been investigated. Experiments have been made in range of nucleation rates from to at temperatures close to the critical line. The results of experiments are compared with the homogeneous nucleation theory, which takes into account the main factors limiting the nucleus growth. The effect of the curvature of the nucleus separating surface is allowed for in the nucleation work with the help of the Van-der-Waals-Cahn & Hilliard method. It is shown that the allowance for the curvature effect in the homogeneous nucleation theory improves its agreement with experiment. \\\\expert2\\nbo\\AIP Conf. Proceedings, 2000\\2000. V. 534.
