Fe film samples were prepared by oblique simultaneous evaporation from two sources with an angle Ã between the two planes of incidence, the magnetic anisotropy in the film plane was measured, and the columnar structure was observed by SEM. For samples prepared with ÃÂ¿45Â°, the easy axis of anisotropy and columnar grain alignment are in the direction perpendicular to the plane bisecting the two planes of incidence; for samples with ÃÂ¿45Â°, they are parallel to the bisecting plane. A mechanism of anisotropic arrangement of the columnar grains based on a self-shadowing effect is proposed. The magnetic anisotropy calculated from the columnar structure assuming such a mechanism was in fairly good agreement with the measured anisotropy.
