Ultrathin magnetic films on rhodium substrates — •Ali Al-Zubi, Gustav Bihlmayer, and Stefan Blügel — Institut für Festkörperforschung, Forschungszentrum Jülich, D-52425 Jülich

Using density functional theory calculations we investigate relaxations, magnetic order, and the magnetic anisotropy energy (MAE) of Fe, Co, and Ni monolayers on Rh(001) and Rh(111) substrates. We employ the full-potential linearized augmented planewave method in thin film geometry. The Co and Ni films were found to order ferromagnetically, while for Fe a tendency towards antiferromagnetism is observed. We compare to the Fe/Ir(111) system, where more complicated spin-structures were observed in theory and experiment [1]. Especially for Co films we find very large induced moments in Rh, therefore we study the substrates influence on the MAE and compare also to the case of Co/Ir(111).
