Abstract :
A convenient way of controlling the magnetic anisotropy of electrodeposited cobalt nanowires was studied. The nanowires were grown by electrodeposition into the cylindrical pores of a polycarbonate membrane. Using ferromagnetic resonance and transmission electron microscopy, it was demonstrated that changes in the two main electrodeposition parameters (electrolyte pH and deposition rate/current density) leads to modifications of the crystallographic structure of the nanowires that can be grown in cubic (FCC) or hexagonal (HCP) phases.
