Local atomic structure of Fe-Ni/V multilayer nanostructures: EXAFS spectroscopy and synchrotron radiation data
- 59 Downloads
Fe, Ni, and V K EXAFS spectroscopic experiments were carried out at the European Synchrotron Radiation Center (ESRF) in the fluorescent mode on the 26 Å line with the use of the [(Fe82Ni18)5/V6]25 and [(Fe82Ni18)10/V6]25 samples of multilayer nanoheterostructures prepared by magnetron spraying (at Uppsala University). The partial interatomic distances were determined by the regularization technique. The existing distortions of the bcc lattice in (Fe82Ni18)/V multilayer nanostructures depend strongly on the thickness of the ferromagnetic layers of the permalloy and also affect vanadium layers.
