摘要：

The relationship between structural and magnetic properties was examined for epitaxial Fe(001) films with 500 angstrom to 1 mum thickness on MgO(001) substrates prepared by the ion beam sputtering technique. Lattice spacing perpendicular to the (001) plane of as-deposited Fe films was found to be longer by 1.4 to 2% than the lattice parameter of bulk Fe. The shapes of M-H curves for those Fe films changed from square to step type with increasing film thickness. Stripe domain was observed for films with step-type hysteresis loops. The appearance of the stripe domain was clearly explained by the perpendicular magnetic anisotropy induced by the tension of the lattice.
