Critical and quantum critical spins fluctuations in URhGe

DOI

Ferromagnetism in URhGe is continuously suppressed with a magnetic field leading to a Quantum Critical Point (QCP) at around 12 T engulfed by a pocket of superconductivity. The long term aim of the project is to establish if and how quantum critical fluctuations bring about the superconductivity. This proposal is to measure the amplitude, characteristic length and energy scale of critical fluctuations at temperatures near the Curie temperature of 9.5 K in zero magnetic field. Several features of the critical scattering such as strong non-Landau damping are expected to be observed in contrast with the case of d-metal magnets. Measurement of the evolution of the energy and length scales with magnetic field will be the subject of a future proposal to determine changes in the fluctuations approaching the QCP and to relate these to the appearance of superconductivity at high field.
