Magnetism of 3d-transition metals on Rh(100) — •Ali Al-Zubi, Gustav Bihlmayer, and Stefan Blügel — Institut für Festkörperforschung, Forschungszentrum Jülich, 52425 Jülich

Motivated by recent publications [1,2] reporting on unexpected magnetic properties of ultrathin magnetic films on 4d and 5d metal substrates, we employ DFT in conjunction with the full-potential linearized augmented plane wave (FLAPW) method implemented in the FLEUR code to study systematically the magnetic properties of the 3d transition-metal (V, Cr, Mn, Fe, Co and Ni) monolayers on the Rh(100) surface. Including relaxations, we predict a ferromagnetic (FM) ground state for V, Co and Ni, while Cr, Mn and Fe favor the c(2×2) antiferromagnetic (AFM) state. The unexpected c(2×2) AFM for Fe encouraged more detailed investigations of this system such as e.g. the row-wise AFM p(1×2) order. The role of the hybridization between the monolayers and the Rh substrate is analyzed by comparing the results to those of 3d monolayers on Ag(100) and Pd(100).
