(2012-05-22)This thesis presents the direct observations of magnetic flux vortices in superconducting weakly coupled arrays. Real space images of vortices were obtained for various values of f, the fractional flux per unit cell in ...
Vortex distributions and dynamics in superconductors near surface steps and sample edges studied by scanning SQUID microscopy and critical current measurements (2000)We have studied the interactions of vortices in superconductors with surface features and sample edges. Surface steps can generate an asymmetric vortex pinning potential and can influence the distribution of vortices upon ...
