Abstract Scope FeCo alloy mesochains were developed under external magnetic field influence by co-precipitation chemistry. The as-synthesized soft ferromagnetic FeCo alloy mesochains possessed a saturation magnetization value, Ms, of 205 emu/g and a coercivity, Hc, of 150 Oe at 300 K. Annealed (1000 K) FeCo mesochains possessed an Ms of 212 emu/g with Hc of 120 Oe. The FeCo alloy mesochains were found to form into continuous microwires upon annealing. In sufficient concentrations, the mesochains may be formed into rigid 3D microstructures once the forming matrix is removed by heat. In contrast, the high aspect ratio FeCo alloy structures could prove useful for applications in magnetic switching devices and radar absorbent materials when applied and oriented to coatings at the surface.
