Nanocomposite magnetic materials, methods of manufacturing nanocomposite magnetic materials, and magnetic devices and systems using these nanocomposite magnetic materials are described. A nanocomposite magnetic material can be formed using an electro-infiltration process where nanomaterials (synthesized with tailored size, shape, magnetic properties, and surface chemistries) are infiltrated by electroplated magnetic metals after consolidating the nanomaterials into porous microstructures on planar substrates. The nanomaterials may be considered the inclusion phase, and the magnetic metals may be considered the matrix phase of the multi-phase nanocomposite.
