英文摘要
We have studied coexistence of ferromagnetism and superconductivity in ferromagnetic superconductor of UCoGe from the microscopic NMR measurement using a high-quality single crystal. Below the ferromagnetic transition, whole region of the sample is in ferromagnetic state, and a nearly half of the region becomes superconductive below Tc. We also have investigated magnetic fluctuations in the compound, and found that longitudinal ferromagnetic fluctuations along the ordered moments directed to the c axis is dominant at low temperatures. The magnetic fluctuations we observed have been suggested to be favorable for spin-triplet superconductivity from theoretical point of view. These results suggest the possibility that spin-triplet superconductivity is realized in UCoGe.
