摘要：

We have recorded magnetic speckle patterns of unprecedented quality on a tiny sample using soft-x-ray resonant magnetic scattering in reflection geometry. This geometry is well suited to the study of epitaxial thin films. The microscopic object consisted of an FePd wire with transversal stripe domains of alternatingly up and down magnetization. Sharp magnetic superstructure peaks reflect the domain periodicity, whereas the magnetic speckles give access to the domain morphology. A high degree of coherence has been obtained (beta=0.85) as evidenced from the strong observed intensity fluctuations.
