Uniaxial magnetic anisotropy in epitaxial α-Fe(math formula) films



The magnetic anisotropy of epitaxial, high-index Fe(math formula) films is investigated. The strength of the in-plane uniaxial magnetic anisotropy increases monotonically with the inclination angle φ between Fe(001) and Fe(math formula). This increase is demonstrated to be caused by the cubic magnetocrystalline anisotropy and not by surface- or interface-related effects.
