Abstract
Clean magnetic superconductors are considered in which the phase transition into the ferromagnetic state takes place at a temperature ϑ in the absence of superconductivity, with ϑ≪T c1, whereT c1 is the superconducting critical temperature. The exchange and electromagnetic interactions of electrons and localized magnetic moments are taken into account, as well as magnetic anisotropy. We show that below the temperatureT M≈ϑ in the superconducting state the inhomogeneous magnetic structure of transverse one-dimensional domain type (DS phase) should occur at real values of the exchange interaction and anisotropy. In the DS phase gapless superconductivity is realized at temperatures sufficiently far fromT M. Here the equilibrium direction of the magnetic structure wave vectorQ can be changed by applying a supercurrent across the sample. The behavior of this DS phase in an external magnetic field is also considered.
