The in-plane rotation of magnetic stripe domains in a 65-nm magnetostrictive Fe0.8Ga0.2 epitaxial film was investigated combining magnetic forcemicroscopy, vibration samplemagnetometry, and x-ray resonant magnetic scattering measurements.We analyzed the behavior of the stripe pattern under the application of a bias magnetic field along the in-plane direction perpendicular to the stripe axis, and made a comparison with the analogous behavior at remanence. The experimental results have been explained by means of micromagnetic simulations, supported by energy balance considerations. Fields smaller than ∼400 Oe do not induce any stripe rotation; rather, a deformation of the closure domains pattern was evidenced. Larger fields produce a sudden rotation of the stripe structure.

Abstract

The in-plane rotation of magnetic stripe domains in a 65-nm magnetostrictive Fe0.8Ga0.2 epitaxial film was investigated combining magnetic forcemicroscopy, vibration samplemagnetometry, and x-ray resonant magnetic scattering measurements.We analyzed the behavior of the stripe pattern under the application of a bias magnetic field along the in-plane direction perpendicular to the stripe axis, and made a comparison with the analogous behavior at remanence. The experimental results have been explained by means of micromagnetic simulations, supported by energy balance considerations. Fields smaller than ∼400 Oe do not induce any stripe rotation; rather, a deformation of the closure domains pattern was evidenced. Larger fields produce a sudden rotation of the stripe structure.
