The magnetic flux penetrating a superconductor is represented as a set of flux lines, interacting with each other through a realistic potential derived from Ginzburg-Landau theory and with a random pinning potential. The effects of temperature are simulated by a stochastic Langevin force. Initial ca
We have spectrum analysed the voltage induced in a pick-up coil wound around a cylindrical bulk sample of YBa2Cu307\_~ when driven by a weak low frequency AC magnetic field, superimposed on a weak DC magnetic field, at 77 K. The harmonics generated by the highly nonlinear response are explained quan
The invited talk was given by the author. ## Study of tlux motion and resistance in the new superconductors is of interest both for achievement of usefully low resistance at usefully large current densities, and for conceptual understanding of the idealized resistive behavior in the zero current
A magneto-optical high resolution technique is described which uses Bi-containing ferrogarnet film as an indicator. The technique was used to visualize and make topograms of the magnetic flux distribution in the vicinity of high temperature superconductors over a wide range of temperatures (5 -300 K
