Title

Search for a magnetosuperconducting domain dependence of the Zeeman splitting in the unconventional superconductor CeCoIn5

Abstract

The aim of the proposal is to investigate the link between the spin resonance of the unconventional superconductor CeCoIn5 and the field induced magnetic ordering occurring within the superconducting phase. For certain directions of the magnetic field, the ordering occurs only within a single magnetic K-domain selected by superconducting properties, namelly the topology of the superconducting gap. We would like to investigate if a similar selection occurs for the Zeeman splitting of the spin resonance. This would give strong support to the theoretical scenario of a condensation of the spin resonance into a static magnetic order under magnetic field.
