Internal magnetic field of superconducting ferromagnets

[摘要] We have measured the nonlinear response to the ac magnetic field in the superconducting weak ferromagnet Ru-1222, at different regimes of sample cooling which provides unambiguous evidence of the interplay of the domain structure and the flux distribution in the superconducting state. This is a proof of coexistence of ferromagnetic and superconductive order parameters in high-T-c ruthenocuprates.
