Ferromagnetism and Superconductivity in Uranium Compounds

Abstract

Recent advances on ferromagnetic superconductors, UGe2, URhGe and UCoGe are\npresented. The superconductivity (SC) peacefully coexists with the\nferromagnetism (FM), forming the spin-triplet state of Cooper pairs. The\nstriking new phenomena, such as SC reinforced by the magnetic field, are\nassociated with Ising-type ferromagnetic fluctuations. A variety of\nferromagnetic ordered moments between UGe2, URhGe and UCoGe affords to\nunderstand the relation between FM, tricriticality and SC.\n
