Density-functional study of oxidation at the Mn-Co interface

Original language description

By using first-principles plane-wave pseudopotential code, we study deposition of Mn on ultrathin fcc Co(001) films, and the effect of oxygen on the Mn-Co coupling. First, in agreement with experiments and recent calculations, we find the MnCo(2x2) alloyoverlayer with ferromagnetic coupling of all spins as the most stable structure. The conclusion remains, however, unchanged after deposition of a full oxygen overlayer, leaving thus unexplained the experimentally observed Mn antiferromagnetic moment alignement. For more complicated structures we get clear indication that superexchange in Mn-O-Co groups can stabilize the Mn-Co antiferromagnetic coupling.
