Abstract

In high-(Formula presented) superconducting compounds (Formula presented) the onset of superconductivity occurs at a temperature (Formula presented) much lower than the temperature of the phase transition to weak ferromagnetism, and the diamagnetic response arises at the temperature (Formula presented) which is much lower than (Formula presented) The present paper contains experimental data and a theoretical analysis of this phenomenon. These results collectively show convincingly that between (Formula presented) and (Formula presented) vortices are present in the sample in equilibrium without an external magnetic field (the spontaneous vortex phase).
