In this study, using a single crystal of URhGe, we performed zero-field NMR study under uniaxial stress. For all the observed NMR peaks, a successive shift toward lower frequencies has been ob- served with increasing the uniaxial stress. The behavior indicates uniform and successive change of local environments at the nuclear positions. Simultaneously, however, we have also seen a broadening of the NMR peaks with increasing the stress, in particular above 0.8 GPa, suggesting the distribution of the local environments with larger stresses.

Recently, uniaxial stress has been found to be a remarkable tool for tuning the pairing strength in a ferromagnetic superconductor URhGe. A relatively small uniaxial stress applied along the 
crystal axis changes the superconducting (SC) phase diagram significantly, merging the low-field SC and reentrant SC domes, with a large enhancement of 
. The increases both at zero field and under a field, reaching 1 K, more than twice higher than at ambient pressure. This enhancement of SC has been shown to be directly related to a change of the magnetic dimensionality, moving the system away from the Ising-type limit, which results in the rapid decrease of the 
. In this study, by means of zero-field 
Ge NMR in the ferromagnetic state, we have investigated the effects of uniaxial stress on the electronic state of URhGe.
