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.
