  We analyze antiferromagnetism in $f$ electron superlattices. We show that the
competition between the Kondo effect and the RKKY interaction in $f$ electron
materials is modified by the superlattice structure. Thus, the quantum critical
point which separates the magnetic phase and the Fermi liquid phase depends on
the structure of the $f$ electron superlattice. The competition between the
Kondo effect and the RKKY interaction is also reflected in the magnetic
interlayer coupling between different $f$ electron layers. We demonstrate that
in the case of weak Kondo effect the magnetic interlayer coupling behaves
similar to other magnetic heterostructures without Kondo effect. However, close
to the quantum phase transition, the dependence of the interlayer coupling on
the distance between the $f$ electron layers is modified by the Kondo effect.
Another remarkable effect, which is characteristic for $f$ electron
superlattice, is that the magnetic interlayer coupling does vanish stepwise
depending on the distance between different $f$ electron layers. As a
consequence, the quantum critical point depends also stepwise on this distance.
