Physical Society ColloquiumInterview for Faculty PositionCoexistance of Magnetic Correlations and Superconductivity in the Vortex State of High Temperature SuperconductorsVesna MitrovicCNRS, GrenobleThe proximity of antiferromagnetism and superconductivity in the phase diagram common to all the high temperature superconductors(HTS) has long suggested an interesting interplay between antiferromagnetism (AF) and superconductivity. Does some form of AF or AF-fluctuations coexist with superconductivity deep in the superconducting state? Another important question is to understand the nature of these magnetic correlations both in the regions where the superconducting order parameter in maximum and where it is weakened, as is the case in the vortex cores. Many theories have suggested that AF or spin density waves can be established in the cores of vortices and coexist with superconductivity. Recent experiments seem to confirm these ideas. Theoretical predictions for the existence of the vortex core magnetism and recent experimental evidence will be discussed. In particular, the discussion will
