Kurzfassung englisch:
Amorphous magnetic ribbons represent both novel technologically relevant complex samples which are currently in the process of material development for use as magnetic sensors and actuators due to their exceptional magnetostriction properties as well as illustrative examples for developing the technique of ultra-small-angle polarised neutron scattering (USANSPOL) for the study of magnetic microstructure. We present the formalism on which the USANSPOL technique is based and highlight a potential route on which USANSPOL data analysis may be performed. Experimentally obtained scattering patterns are the results of a variety of parameters like material composition and production conditions as well as various environmental conditions, including zero-field environment, the influence of external magnetic field, mechanically induced stress, or a combination of both effects, and in magnetically saturated state. In the case of non-isotropic structures a two-dimensional record of the scattered neutron intensity is essential and more complexity is added by the special features of magnetic neutron scattering and the USANSPOL technique itself. In this work we concentrate on these peculiarities and describe the current experimental status which is driven by the underlying USANSPOL scattering formalism. Recent experimental results are presented to illustrate the phenomenological correspondence to our modelling.
