The control of magnetic anisotropy has been the driving force for the development of magnetic applications in a wide range of technological fields from sensing to spintronics. In recent years, the possibility of tailoring the magnetic properties goes together with a need for new 3D materials to expand the applications to a new generation of devices. Herein, the possibility of designing the magnetic anisotropy of 3D magnetic nanowire networks is shown just by modifying the geometry of the structure or by composition. It is also shown that this is possible when the magnetic properties of the structure are governed by magnetostatic anisotropy. The present approach can guide systematic tuning of the magnetic easy axis and coercivity in the desired direction at the nanoscale. Importantly, this can be achieved on virtually any magnetic material, alloy, or multilayers that can be prepared inside porous alumina. These results are promising for engineering novel magnetic devices that exploit tailored magnetic anisotropy using metamaterials concept.
