Effect Theory

The behavior of the perpendicular upper critical field in high T c superconductors is studied theoretically. It is shown, within proximity effect theory, that a substantial deviation from intrinsically linear behavior of [Formula: see text] near T c can occur when imperfections exist in single crystals. A positive curvature arises if there is a competition of superconductivity of two different superconducting phases — the bulk and the defect — in the specimen.
