PhD project: The competition between magnetism and superconductivity in a d-wave superconductor

Project description

CeCoIn5 is a clean d-wave superconductor with a superconducting transition of 2.3 K. The transition temperature is one of the largest for a heavy fermion system. Cerium magnetism plays a key role in this system as evidenced by the presence of a large magnetic resonance peak in the neutron response in the superconducting state. On doping with Hg, the superconductivity is suppressed and static magnetism is onset. The goal of this proposal is to investigate the critical properties of this transition using thermodynamic and neutron scattering measurements. The project will involve low temperature work and also scattering measurements at large scale facilities.
