Impurity-induced broadening of the transition to a Fulde-Ferrell-Larkin-Ovchinnikov phase

Abstract

Recent study on doping effects in the heavy fermion superconductor CeCoIn${}_5$ has shown that a small amount of doping induces unexpectedly large broadening of the second order transition into the high field and low temperature (HFLT) phase of this material. Motivated by this observation, effects of quenched disorder on the second order transition into a longitudinal Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state are examined. The observed large broadening of the transition is naturally explained as a consequence of softness of each FFLO nodal plane. The present results strongly support the scenario identifying the HFLT phase of CeCoIn${}_5$ with a longitudinal FFLO vortex state.
