Abstract

Intrinsic biquadratic interlayer coupling in magnetic layered structures is analysed theoretically within the spin-polarized free-electron approximation.The corresponding coupling parameter oscillates with the interlayer thickness with the oscillation period equal to half of that for bilinear term.An extrinsic mechanism following from a competition between the intra-and interlayer exchange coupling is also discussed.
