Description |
The coexistence of ferromagnetism and superconductivity(SC) in three uranium compounds UGe2, URhGe and UCoGe attracts much interest, because the spin-triplet state with equal spin paring and the unusual field-induced phenomena are realized. Their ordered moments are 1.5, 0.4 and 0.05 muB, respectively, and the 5f electrons with itinerant nature are believed to be responsible both for magnetism and for superconductivity. We focus on pressure (P) and magnetic field (H) response on the magnetic fluctuations and Fermi Surfaces and their feedback on superconductivity. |
