      abstract     = {Using spin density functional theory (SDFT) calculations,
                      we have studied the magnetic states, including collinear and
                      noncollinear magnetic interlayer coupling, of Fe1−xCox
                      ultrathin films sandwiching Rh(001) layers. We found very
                      large values for the interlayer exchange coupling (IEC) in
                      Co/Rhn/Co or (FeCo)m/Rhn/Co structures as compared to, e.g.,
                      Ag or Au spacer layers. The IEC oscillates with the Rh
                      spacer thickness showing a transition between strong
                      antiferromagnetic and ferromagnetic coupling between five-
                      and seven-layer thickness of the Rh film. Moreover,
                      depending on the thickness of the FeCo film, a reorientation
                      transition between in-plane and out-of-plane easy axis was
                      found when spin-orbit coupling is considered in the
                      calculations. This result suggests that, for specific
                      arrangements such as (FeCo)2/Rh5/Co structures, a
                      competition between IEC and magnetic anisotropy of coupled
                      films may result in noncollinear ordering. This possibility
                      was studied with constrained, noncollinear SDFT calculations
                      and the results were mapped onto a classical spin model to
                      explore the richness of spin structures that can arise in
                      these multilayer systems.},
