Phenomenological theory of ferromagnetic superconductivity.
It is argued that the pairing symmetry realized in a ferromagnetic superconductor UGe(2) must be a nonunitary triplet pairing. This particular state is free from the Pauli limitation and can survive under a huge internal molecular field. To check our identification we examine its basic properties and several experiments are proposed. In particular, the external field is used to raise T(c) by controlling the internal spontaneous dipole field.
