pH-Controlled electrodeposition of diameter-modulated Co nanowires: crystal texture and magnetic properties

-axis perpendicular to the nanowires and yielding a competition between shape and magnetocrystalline anisotropies, whereas at pH = 4.0, polycrystalline nanowires have no defined magnetocrystalline easy axis. For both pH values, a significant magnetostatic energy term is concluded, arising from the shape anisotropy of individual nanowires and significant interactions among neighboring DM nanowires.
