| 總結: | Anisotropic and giant magneto-resistance (AMR and GMR) measurements for a molecular beam epitaxy grown (110) multilayer film [50 Å-DyFe 2/50 Å-YFe2] × 40 at 100 K are reported. The film possesses a bending field BB∼5T and an irreversible switching field BIS∼5T. These features allow the study of both AMR, and GMR caused by the creation not only of longitudinal but also transverse magnetic exchange springs, in the magnetically soft YFe2 layers. Finally, rotation experiments in applied fields show that like DyFe 2 films, there is a metastable state aligned along a [1̄ 1 0] axis at 100K. © 2004 Elsevier B.V. All rights reserved.
