The theory is based on a model of the charge-induced spin density wave (SDW) formed in the chromium layer. It is shown that the effective magnetic coupling between thick ferromagnetic layers arises due to variations of the SDW vector orientation in the antiferromagnetic layer over a characteristic length zeta determined by the exchange stiffness of chromium. A general expression for the effective magnetic coupling energy E(psi) as a function of the angle psi between magnetic moments of the ferromagnetic layers is obtained and numerically analyzed for an arbitrary value of the parameter rhozeta, where rho is the density of monoatomic steps on the interface. For rhozeta much greater than 1, the form of E(psi) is typical of a model with the "biquadratic" interaction, while in the case of rhozeta much less than 1, the dependence obtained differs significantly. The proposed mechanism is used to interpret the results of measurements of the interlayer exchange coupling in Fe/Cr(001) structures. (C) 2004 MAIK "Nauka/Interperiodica".
