Theoretical study of induced V polarization at the interface with Fe in FenVm superlattices

摘要

Recent experimental and theoretical studies have displayed induced V polarization in FenVm superlattices. We have performed TB-LMTO calculations of Fe5Vm following the experimental configuration of Tomaz et al. (1997, J. Phys. condens. Matter, 9, L179). We found a short-range induced polarization of V in agreement with previous calculations (Hamada et al. 1984 J. Phys. F, 14, 2371; Vega et al. 1991 J. appl. Phys., 69, 4544; Coehoorn 1995, J. Magn. magn. Mater., 151, 341) but in disagreement with Tomaz et al. Both (001) and (011) crystallographic orientations have been studied. [References: 12]
