通过磁力显微镜在分子束外延生长的有序 FePd 薄膜中观察到小磁畴（70 nm）。这些层表现出由单轴 Ll(0) [CuAu(I) 型] 化学排序引起的垂直磁各向异性。磁化曲线显示易磁化轴垂直于薄膜平面，并且用微磁模型对其进行解释可以得出正确的磁畴尺寸。
Small magnetic domains (70 nm) have been observed by magnetic force microscopy in ordered FePd thin films grown by molecular-beam epitaxy. The layers exhibit a perpendicular magnetic anisotropy induced by uniaxial Ll(0) [CuAu(I)-type] chemical ordering. The magnetization curves show that the easy magnetization axis is perpendicular to the film plane and their interpretation with a micromagnetic model leads to the correct size of the domains.
