✦ Synopsis

The first observation of a new physical phenomenon -appearance of macroturbulence in type-II superconductors -is reported. It is found that during the remagnetization of high-To single crystals in some temperature range the flux lines are condensed into "drops" of increased density which then move as hydrodynamical vortices. The observed structures are treated as the development of current instability resulting in the formation of turbulent current structures.
