Magnetic order and superconductivity in LSCO: a review

Abstract

High-Tc copper oxides of the LSCO family show a very clear case of competition between antiferromagnetic (AF) order and superconductivity. Magnetic order can, however, coexist with superconductivity, and the experimental evidence for frozen magnetic moments in superconducting samples is reviewed here. The primary characteristics of the magnetic order are summarized and some open questions are outlined, particularly concerning the intrinsic or extrinsic nature of this order around x=0.12.
