Novel angular anisotropy in polarized SANS

Abstract: The aim of this proposal is to experimentally observe a hitherto unseen angular anisotropy in the polarized SANS cross section of a magnetically strongly inhomogeneous material. Based on the micromagnetic SANS theory, the difference between the spin-up and spin-down SANS cross sections is expected to show a clover-leaf-type angular anisotropy with maxima roughly along the diagonals of the detector. The effect is particularly pronounced in inhomogeneous magnetic materials such as nanoporous ferromagnets or nanocomposites. We aim to carry out the experiment on the two-phase nanocrystalline soft magnetic alloy Nanoperm, a material that finds widespread application as magnetic core in high-frequency power transformers. The present proposal addresses a fundamental question related to the angular anisotropy of the polarized SANS cross section.
