Direct observation of the Abrikosov vortices in the single crystal of a high-temperature superconductor YBa2Cu3Ox
Vinnikov L. Ya. , Gurevich L. A. , Emel'chenko G. A., Osip'yan Yu. A.
The magnetic structure of a YBa2 Cu3 Ox single crystal was studied by decorating it with disperse ferromagnetic particles. The magnetic-flux distribution patterns with a resolution of the Abrikosov vortices, whose rows are oriented principally along the twinning boundaries, have been obtained.
