摘要: Abstract Magnetic nanocomposite materials are of interest for applications including power inductors and transformers, where a combined large bandwidth, low loss, relatively high permeability desired. This work demonstrates the fabrication nickel/iron-oxide nanocomposites, up to ~3 μm thick, permalloy/iron-oxide ~1 μm using an electro-infiltration process, whereby voids in iron-oxide nanoparticle film filled with electroplated metal. Measurements show that magnetic nanocomposites exhibit hybrid properties: modestly saturation attributed metal matrix phase, but increased bandwidth inclusion phase. At 10 MHz, material exhibits relative ~23, loss tangent around 0.1; ~136, 0.15.
