Fe/Ir superlattices : growth, structure and magnetic properties
Résumé
The study of structures and magnetism of FeIr(001) superlattices leads us to observe three different cases. First, for Fe thicknesses up to 4 planes, Fe is of bct structure with an fcc Ni-like magnetic anisotropy. Second, for thick Fe layer, Fe is bcc and an antiferromagnetic coupling is observed. Third, for thin Ir layers, Ir is strained and plays an inportant role in magnetic behaviour.
