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
with
,
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.
