Oscillations of the magnetic moment and strong diamagnetism in a medium containing superconducting states localized in dislocation loops
Nabutovskii V.M., . Shapiro B. Ya
Oscillations of the magnetic moment in a superconducting state localized near a dislocation loop are examined. It is shown that the dependence of the critical temperature on the magnetic field oscillates. When dislocation loops of approximately the same size produce a medium, strong diamagnetic effects occur in it and instabilities appear in a number of cases. The investigation is conducted in the framework of the Ginzburg-Landau equation.
