ResumenArrays of hexagonally ordered Fe28Co67Cu5 nanowires with tailored diameter from 18 to 27 nm were prepared by electroplating into anodic alumina templates and annealed in the temperature range of 300-600°C, preserving but refining their bcc crystal structure. Despite the partial reduction of saturation magnetization and corresponding shape anisotropy after annealing at 500°C, larger coercivity, 0.36 T, and squareness ratio, Mr/Ms = 0.98, were obtained. This unexpected behavior is interpreted through micromagnetic simulations where the magnetic hardening is associated with the transition from vortex to transverse domain-wall reversal modes connected with the reduction of saturation magnetization. Simulations also predict a significant coercivity increase with decreasing nanowires diameter which agrees with experimental data in the overlapping diameter range. © 2013 AIP Publishing LLC.
