Summary This work provides an electrodeposition‐based methodology for synthesizing multicomponent nanowires containing Ag, Co and Ni atoms. Nanowire morphology was obtained by using an anodic alumina membrane with cylindrical pores of ∼200‐nm diameter. Structural, compositional and magnetic characterization revealed that the as‐synthesized nanowires adopted a core–shell microstructure. The core (axial region) contained pure Ag phase volumes with a plate‐like morphology oriented perpendicular to the nanowire axis. The shell (peripheral region) contained pure Ag nanoparticles along with superparamagnetic Co and Ni rich clusters.
