Abstract

We report a study on the interplay between antiferromagnetism (AFM) and superconductivity (SC) in CeRhIn5 under pressure P = 1.75 GPa. The onset of the magnetic order is evidenced from a clear split of 115In-NQR spectrum due to the spontaneous internal field below T N = 2.5 K. Simultaneously, bulk SC is demonstrated by the observation of the Meissner diamagnetism signal whose size is the same as in the exclusively superconducting phase. These results indicate that the AFM coexists homogeneously with the SC at a microscopic level.
