Abstract
To study the recently observed displacive reconstruction of the two-layer Fe film on Cu(001), a highly simplified tight-binding Hamiltonian is analyzed by the recursion method. In a narrow range of magnetization (probably ≳ per atom), the surface reconstruction is likely to develop.
Résumé
Afin d'étudier la reconstruction displacive d'un film bicouche de Fe sur du Cu(001), récemment observée, nous avons analysé un hamiltonien hautement simplifié de liaison forte par la méthode de récurrence. La reconstruction de surface se développe vraisemblablement dans une gamme étroite d'aimantation (probablement ≳ par atome).
