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
The time dependence of the local magnetic flux density B (r, t) and of the magnetic flux β’ (t) is observed directly and dynamically in epitaxially grown high temperature superconducting thin films using the high resolution magneto-optical Faraday effect. After zero field cooling and application of a
