Abstract
X-ray and polarized neutron scattering techniques have been used to examine the magnetic structure of wide-ribbon Fe78Si9B13 commercial metallic glass (METGLAS® 2605-S2). Samples with well-defined geometry have been made for the experiments at 300 K and in 1.1 T and have been measured in the As-received, Field Annealed and Stress Relieved states. The data show that all three samples are spatially correlated non-collinear ferromagnets. A new method of analysis has been applied to show that the non-collinear components of the moments are correlated over several neighbour spacings, 50% of the range of the atomic correlations, and that, while annealing treatments do not have a profound effect on the correlations, the non-collinear components are larger in the annealed samples.
