Soft Magnets: Fe-Si Alloys and Magnetoelastic Effects

This lecture covers the technologically relevant soft-magnetic materials, focusing on Fe-Si alloys and their materials science aspects. It discusses the properties of Fe-Si alloys, the effects of silicon content, and the processing of oriented and non-oriented steel. The lecture also explores the optimization of soft magnets, including impurities control, grain size, and crystallographic texture. Additionally, it delves into magnetoelastic effects, such as magnetostriction, and their impact on the functional properties of ferromagnetic materials.
