1. A method comprising:
providing a component comprising a soft magnetic alloy with a crystal structure having long-range atomic order; and
treating a surface portion of the component with a high energy beam, thereby melting and solidifying the surface portion to provide a treated surface portion, wherein the treated surface portion comprises a disordered surface layer having a grain size less than about 10 μm in size and a thickness of between 10 μm and 300 μm.
