Influence of twin structure on flux turbulence near the front of vortex annihilation

The remagnetization of YBCO single crystals is studied by magneto-optical technique. Different behavior of the annihilation flux front in twinned and twin-less samples is observed. The specific induction distribution, called the Meissner hole, is found to be necessary forerunner of turbulence develo...

Description
Summary:The remagnetization of YBCO single crystals is studied by magneto-optical technique. Different behavior of the annihilation flux front in twinned and twin-less samples is observed. The specific induction distribution, called the Meissner hole, is found to be necessary forerunner of turbulence development.
