Abstract

An anomalous temperature dependence of 115 In-NMR spectrum is observed in the newly-discovered high field and low temperature superconducting phase of CeCoIn5. The anomalies near the upper limit of Hc2 are attributed to spatially-distributed local density of states of quasiparticles. From a simulation with the phenomenological model for the sinusoidally-modulated superconducting order parameter, the present NMR study provides a microscopic evidence that the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is realized at the high field phase in CeCoIn5
