Ordering and magnetostriction in Fe alloy single crystals

► A review of nature of ordering in bcc lattices of Fe-based alloys is presented. ► Analysis of ordering in Fe alloy single crystals using data from XRD and other methods. ► Current understanding of ordering and its influence on magnetostriction in Fe alloys is presented. ► Lattice strain modulations from the nature of solute atom distribution impact magnetostriction. ► Need for examinations of local atomic environments and ordering using single crystals emphasized.
