Beschreibung
Zusammenfassung:	Sr2RuO4 is an unconventional superconductor with a superconducting transition temperature of 1.5 K. The formation of vortex chains in Sr2RuO4 is observed, they have been directly imaged by muSQUID force microscopy at low temperature. Ginzburg-Landau theory for anisotropic superconductors is in qualitative agreement with the observed dependencies of the vortex chains on the variation of the tilting angle or the amplitude of the external magnetic field.
