      abstract     = {The objective of this work is to employ spin-polarized
                      density functional theory (sDFT) calculations for the
                      exploration of ultrathin magnetic films with large magnetic
                      moments and a strong perpendicular anisotropy. Monolayer
                      films of Fe1-xCox (with x = 0, 0.25, 0.5, 0.75, and 1) on
                      Rh(001) were addressed to study their magnetic properties
                      using the all-electron full-potential linearized augmented
                      plane wave (FLAPW) method in film geometry. We studied the
                      magnetic order of these films including structural
                      relaxations of the topmost layers. Fe1-xCox monolayer films
                      were found to be ferromagnetic (FM) in a broad range of Co
                      content x with a maximum magnetic moment of 2.8 mu(B) and of
                      an out-of-plane magneto-crystalline anisotropy of 0.25 meV
                      per magnetic atom at x = 0.5. The sDFT results were mapped
                      onto a classical Heisenberg model, demonstrating FM Fe-Co
                      and Co-Co couplings, while the Fe-Fe interaction is
                      antiferromagnetic on Rh(001). The ordering temperature of
                      the FeCo film was estimated to be well above room
                      temperature (482 K).},
