We have shown in a previous paper that iron can be grown in a low-spin
ferromagnetic bet phase in (100) Felr superlattices. Additional resul
ts on this system are given in this paper. The very good quality of th
e superlattices is shown to be due to the two-dimensional growth of bo
th Fe on Ir and Ir on Fe. The ferromagnetic order is confirmed by Arro
tt plot experiments. Two magnetically dead layers are observed, which
makes theoretical analysis of the magnetic properties difficult.
