Magnetic Properties of FEXMN1-X/IR(100) Superlattices.


We have produced pseudomorphic FexMn1-x/Ir(100) superlattices having different stoichiometry (0.8 ≥ x ≥ 0.3). The alloy crystalline structure is body centered tetragonal with a c/a ratio between 1.18 and 1.26. Iron rich alloys are ferromagnetic when the corresponding bulk alloys are antiferromagnetic. Manganese rich alloys are certainly antiferromagnetic according to bulk magnetization measurements and Mössbauer effect results. The transition from a ferromagnet with a vanishing moment when x = 0.5 to an antiferromagnet is associated with a volume expansion.
