Abstract: The ground state of an antiferromagnetic atomic chain on a ferromagnetic substrate has been studied taking into account the single-ion anisotropy energy. Qualitatively different behavior of even and odd atomic chains has been demonstrated. A phase diagram in terms of chain length-ferromagnet exchange field has been constructed.
