Antiferromagnetic ordering in the Fe(001) monolayer mediated by the Ir substrate

Original language description

We show that the Fe-monolayer on the fcc(001) surface of iridium has a strong tendency to order antiferromagnetically in the relaxed case. Unrelaxed Fe/Ir(001) sample has the ground state ferromagnetic. The antiferromagnetism is stabilized by layer-relaxations. The relevant part of the present study is the evaluation of pair exchange interactions between Fe-atoms in the Fe-overlayer as a function of increasing model relaxation of first interlayer distance which allows a detailed understanding of the antiferromagnetism of Fe/Ir(001) overlayer. We compare the exchange interactions in the overlayer with interactions in one Fe-monolayer embedded in the Ir crystal where the substrate influence is stronger. Our calculations indicate that in the overlayer aswell as in the embedded monolayer more complex, spiral-like state can be stabilized rather than a simple c(2x2)-antiferromagnetic order.
