Qualitative comparison between experiment and theory. (a)–(d) Two-dimensional experimental polarization of the scattered neutrons of NANOPERM [(Fe0.985Co0.015)90Zr7B3] at a series of applied magnetic fields (see insets). is horizontal in the plane. The range of momentum transfers is restricted to . (e)–(h) Prediction by the analytical micromagnetic theory (no free parameters) using the experimental ratio [equation (63)] and the structural () and magnetic (
A,M0) interaction parameters of NANOPERM [see text, Michels et al. (2012) and Honecker et al. (2013)]. The central white octagons mark the position of the beamstop.
