The field-induced reentrant superconductivity in uranium-based ferromagnet URhGe highlights the close interplay between superconductivity (SC) and magnetism in strongly correlated electron systems. Our NMR experiments in URhGe revealed that the inherent FM fluctuations in URhGe at lower fields is robust to the direction of the applied field, although the field-induced fluctuations at higher fields near HR show strong field-angular dependence. This makes a clear contrast with the case of its sister compound UCoGe, where the FM fluctuations show strong field dependence even at lower fields. We can see that the different character of the FM fluctuations is indeed reflected in their phase diagram of the upper critical field Hc2, which is also unconventional and different between the two compounds. This provides further evidence that the SC is mediated by the FM fluctuations in URhGe and UCoGe.
