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.

A magnetoelectric composition of boron and chromia is provided. The boron and chromia alloy can contain boron doping of 1%-10% in place of the oxygen in the chromia. The boron-doped chromia exhibits an increased critical temperature while maintaining magnetoelectric characteristics. The composition can be fabricated by depositing chromia in the presence of borane. The boron substitutes oxygen in the chromia, enhancing the exchange energy and thereby increasing Néel temperature.

A nanogranular magnetic film includes a structure including first phases comprised of nano-domains dispersed in a second phase. The first phases include at least one selected from the group consisting of Fe, Co, and Ni. The second phase includes at least one selected from the group consisting of O, N, and F.

The magnetic core portion is a multilayer film in which a nanogranular magnetic film and a soft magnetic alloy film are alternately stacked. The nanogranular magnetic film has a structure in which nano-domains of a first phase are dispersed in a second phase. The first phase contains one or more selected from Fe and Co, and the second phase contains one or more selected from O, N, and F. The volume ratio of the first phase to the total volume of the first phase and the second phase is 60% or less. The soft magnetic alloy film contains one or more selected from Fe and Co.

An integrated magnetic device has a magnetic core which includes layers of the magnetic material located in a trench in a dielectric layer. The magnetic material layers are flat and parallel to a bottom of the trench, and do not extend upward along sides of the trench. The integrated magnetic device is formed by forming layers of the magnetic material over the dielectric layer and extending into the trench. A protective layer is formed over the magnetic material layers. The magnetic material layers are removed from over the dielectric layer, leaving the magnetic material layers and a portion of the protective layer in the trench. The magnetic material layers along sides of the trench are subsequently removed. The magnetic material layers along the bottom of the trench provide the magnetic core.
