Pairing mechanism in the ferromagnetic superconductor UCoGe

Experimental identification of pairing mechanism in unconventional superconductors is challenging. Here, Wuet al. show that the field dependence of the pairing strength influences the superconducting upper critical field in UCoGe, suggesting the dominant role of ferromagnetic spin fluctuations.
