Magnetic coupling of 4d transition metal monolayers with bcc-Fe as a substrate

We make a systematic study of 4d transition metal monolayers epitaxially grown on bcc-Fe(001). For this purpose we consider the slabs X/2Fe/X and X/5Fe/X (X = Mo, Tc, Ru, Rh and Pd) within a mean-field Hubbard model. To parametrize the surfaces we add extra orbitals outside the slab to allow for ele...
