Abstract

An inhomogeneous superconducting state under a ferromagnetic molecular field is investigated theoretically. This problem is solved exactly within the mean field approximation for a one-dimensional electron band. It is found that the solution gives a spin modulated structure associated with a spatially inhomogeneous superconducting order parameter and a two-gap structure in the energy spectrum. Experiments on ErRh4B4 are interpreted by this solution.

    Recently a tunneling experiment was done on a polycrystalline ERB. The data shows some unusual structures which may reflect the structure of the density of state for the intermediate phase. L.-J. Lin, A.M. Goldman, A.M. Kadin and C.P. Umbach: Phys. Rev. Lett. 51 (1983) 2151.Google Scholar
