Interlayer exchange coupling: Preasymptotic corrections

Abstract: In the asymptotic limit, the interlayer exchange coupling decays as D −2 , where D is the spacer thickness. A systematic procedure for calculating the preasymptotic corrections, i.e., the terms of order D −n with n ≥ 3, is presented. The temperature dependence of the preasymptotic corrections is calculated. The results are used to discuss the preasymptotic corrections for the Co/Cu/Co(001) system.
