摘要：
Systematic studies on the interplay between the anti ferromagnetic SDW and the superconductivity in Cr1-xRux alloys are reported. The phase transition of the two phases as the function of x appears to be of the first order. The antiferromagnetic SDW is stabilized by the excitonic phase formation competing with the Bose condensation of the superconductivity in Cr1-xRux alloys. (C) 2002 Elsevier Science B.V.
