摘要： An inductor includes a magnetic core portion and a coil portion. 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. The total amount of Fe, Co, and Ni in the soft magnetic alloy film is 70 at % or more.

摘要： 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.

摘要： An electrical steel sheet has a component composition including, by mass %, C: 0.007% or less, Si: 4% to 10%, and Mn: 0.005% to 1.0%, the balance being Fe and incidental impurities, as well as a sheet thickness within a range of 0.01 mm or more to 0.10 mm or less, and a profile roughness Pa of 1.0 μm or less. The electrical steel sheet exhibits excellent iron loss properties whereby the magnetic property is free from deterioration, and degradation of the stacking factor can be avoided, even when the steel sheet with a thickness of 0.10 mm or less has been subjected to siliconizing treatment to increase the Si content in the steel.

摘要： A graphene structure is provided. The graphene structure comprises a substrate layer and at least two graphene layers disposed on the substrate. The at least two graphene layers comprises a gate voltage tuned layer and an effective graphene layer and the effective graphene layer comprises one or more graphene layers. A magnetoresistance ratio of the graphene structure is determined by a difference in a charge mobility and/or a carrier density between the gate voltage tuned layer and the effective graphene layer. The charge mobility and/or the carrier density of the gate no voltage tuned layer is tunable by a gate voltage applied to the graphene structure. A magnetic field sensor comprising the graphene structure is also provided.

摘要： A method of producing bit-patterned media is provided whereby a shell structure is added on a bit-patterned media dot. The shell may be an antiferromagnetic material that will help stabilize the magnetization configuration at the remanent state due to exchange coupling between the dot and its shell. Therefore, this approach also improves the thermal stability of the media dot and helps each individual media dot maintain a single domain state.
