N2 - The indirect RKKY interaction in a layered metal with nearly nested (almost squared) Fermi surface is evaluated analytically. The final expressions are obtained in closed form as a combination of Bessel functions. We show that the expected "2kF" oscillations occur as the far asymptote of our expressions, where the value of the effective Fermi momentum kF depends on the direction in r-space. We demonstrate the existence of the intermediate asymptote of the interaction which is of the sign-reversal antiferromagnetic type. This part of RKKY interaction is the only term surviving in the limit of exact nesting. A good agreement of our analytical formulas with numerical findings is found until the interatomic distances.
