摘要： There is disclosed a thinner-layered radio wave absorber having high absorption performance for a high frequency electromagnetic wave. The radio wave absorber, even when having a magnetic layer of not more than 1 mm in thickness, achieves satisfactory absorption characteristics for the high frequency electromagnetic wave by adopting a structure that a conductor is fixedly attached to a face opposite to an electromagnetic-wave incident face of the magnetic layer of single-layered structure, and also arranging the magnetic layer to have values of a real part &mgr;′ and an imaginary part &mgr;″ of complex relative magnetic permeability of the magnetic layer satisfying an expression of &mgr;″≧m&mgr;′−n (m: real number of m>0, n: real number of n≧0) outside an impedance mismatching region.

摘要： A rolled core is formed by winding a thin body of an amorphous magnetic alloy having positive magnetostriction characteristics so that, of the two surfaces the surface of smaller surface coarseness faces inward. This rolled core is improved in iron loss over a rolled core obtained by winding the thin body so that the surface of greater surface coarseness faces inward. Breakage of the thin body tends to occur less frequently when it is wound so that the surface faces inward.

摘要： For the present ferromagnetic tunnel junction structure, employed is a means characterized by using an MgO barrier and using a Co2FeAl full-Heusler alloy for any of the ferromagnetic layers therein. The ferromagnetic tunnel junction structure is characterized in that Co2FeAl includes especially a B2 structure and one of the ferromagnetic layers is formed on a Cr buffer layer. The magnetoresistive element is characterized in that the ferromagnetic tunnel junction structure therein is any of the above-mentioned ferromagnetic tunnel junction structure. Accordingly, a large TMR, especially a TMR over 100% at room temperature can be attained, using Co2FeAl having a smallest α though not a half-metal.

摘要： A method for producing a magnetic particle forming a magnetic material for absorbing electromagnetic waves comprises the steps of mixing an organometallic complex or a metal salt with a chain polymer and dissolving the mixture in a solvent (step S1); raising the temperature of the mixture to reaction temperature (step S2), carrying out a reaction at the reaction temperature (step S3); and forming the magnetic particle having a structure that the periphery of each fine particle formed from the organometallic complex or the metal salt is surrounded by the chain polymer and recovering the formed magnetic particle after the reaction (step S4). The magnetic particle has a nanogranular structure to become a magnetic material for absorbing electromagnetic waves. Such a magnetic particle is produced by a wet reaction. Thus, a larger amount of magnetic particle can be produced by one reaction.
