摘要
We present results of ab initio calculations for the electronic structure and the magnetic moments of 4d (Ru, Rh, Pd) and 5d transition-metal bilayers (Ir, Pt) on the Ag(001) substrate. The bilayers of Rh, Pd, Ir, and Pt show ferromagnetism, but compared to the monolayers the moments are strongly reduced to less than 0.35μB. This indicates that the magnetism in the 4d and 5d metal films depends critically on the film thickness. These results put a severe upper limit on the experimental imperfections permitted to verify 4d and 5d magnetism. © 1995 The American Physical Society.
