Magnetic spinodal alloys are ideal materials for studying the relationship between the microstructure of an alloy and its magnetic properties. To unravel this relation, a profound knowledge of the chemical as well as the magnetic microstructure, i.e. the magnetic domain structure, is necessary. However, mapping the magnetic domain structure is rarely accomplished even though it is of major interest for both, fundamental research as well as applications using such alloys. In this study, the magnetic domain structure as well as the evolution of the microstructure of spinodally decomposed Cu52Ni34Fe14 alloys is investigated with various modern (scanning) transmission electron microscopy ((S)TEM) methods. The magnetic domain structure was mapped using differential phase contrast imaging (STEM DPC) and magnetic-force microscopy (MFM). The chemical microstructure was determined using high-angle annular dark field imaging (HAADF) and energy-dispersive X-ray spectroscopy (EDXS) elemental mapping. (C) 2022 The Author(s).
