Research Abstract |
We succeeded in growing high quality single crystals of ferromagnetic superconductor UCoGe and URhGe. The Shubnikov-de Haas signal was observed for the first time in UCoGe. From these results, we have clarified that the existence of a small pocket Fermi surface with large cyclotron effective mass. We also clarified that these characteristics of Fermi surface are related with the magnetic anisotropy and superconducting properties closely.
