Epitaxial PtMn/NiFe exchange-biased bilayers containing directly deposited ordered PtMn

Abstract:

PtMnNiFe exchange-biased bilayers have been grown epitaxially on Si (001) using molecular-beam epitaxy. Spontaneous formation of the chemically ordered face-centered-tetragonal phase of PtMn layer was confirmed without postgrowth magnetic-field annealing, whose Ńel axis is perpendicular to the PtMnNiFe interface. The exchange anisotropy field stabilizes above a PtMn thickness of 15 nm which is much lower than that for polycrystalline PtMn-based exchange-biased systems. For comparison, PtMnNiF...
