摘要:
Magnetic materials exhibiting ferrimagnetic and/or superparamagnetic behavior, produced by impregnating porous glasses with iron and, optionally, manganese, cobalt and nickel compounds, reacting the compounds with the porous glass to form bound complexes, heating the glass to expel unreacted organometallics, and further heating to convert the bound complexes to ferrimagnetic and/or superparamagnetic oxide crystallites, are described. Ferrimagnetic iron oxide crystallites exhibiting coercivities above 10,000 Oe can be made.

摘要:
Disclosed herein is a method for producing a spinel ferrite which has a low permeability loss and a low dielectric loss so that the spinel ferrite can be widely used as a material for high-frequency (MHz) electronic components, and a spinel ferrite produced thereby. The method for producing the spinel ferrite comprises the steps of: providing nickel oxide, cobalt oxide, manganese oxide and iron oxide; wet-mixing the nickel oxide, the cobalt oxide, the manganese oxide and the iron oxide in methanol to obtain a mixture; collecting powder from the mixture and drying the collected powder; grinding the dried powder; and heat-treating the dried powder, thereby producing a nickel-manganese-cobalt spinel ferrite having a low permeability loss and a low dielectric loss. The nickel-manganese-cobalt spinel ferrite can be widely as a material for RF electronic components, and when it is applied to an antenna, it can reduce the length of the antenna and improve the bandwidth, efficiency and performance of the antenna.
