Abstract
The current progress of magneto-optical techniques for direct investig ations of magnetic flux structures in type-II superconductors with hig h spatial resolution is presented. Wide possibilities are offered by t he high-resolution Faraday effect technique requiring a thin layer of EuSe as an indicator and the method using ferrimagnetic garnet films w ith in-plane anisotropy. The advantages of both methods are combined t o investigate flux structures of an YBa2Cu3O7 (YBCO) thin film partly irradiated with 25 MeV oxygen ions and for inhomogeneously twinned YBC O single crystals.
