    摘要： A multilayer printed circuit board includes an inner magnetic layer essentially consisting of magnetic material. The inner magnetic layer may be formed by an action of chemical bond or van der Waals force. The inner magnetic layer may comprise a plurality of magnetic units, each of which provides magnetism, and may be formed by magnetically coupling the magnetic units with each other by using a strong interaction. The inner magnetic layer may essentially consist of a ferrite film. The ferrite film may be formed directly on the inner conductive layer by means of an electroless plating method. The ferrite film may essentially consist of an oxide metal composition, the metal composition being represented by the formula of FeaNibZncCod, where: a+b+c+d=3.0; 2.1≦a≦2.7; 0.1≦b≦0.3; 0.1≦c≦0.7; and 0≦d≦0.15.

    摘要： A ferrite material is disclosed, consisting of an oxide metal composition, the metal composition having the formula of FeaNibZncCod, where: a+b+c+d=3.0; 2.1≦a≦2.7; 0≦b≦0.4; 0≦c≦0.4; and 0.1≦d≦0.5. A ferrite film is made of the ferrite material. Preferably, the ferrite film is formed by a ferrite plating method to have a thickness of 30 μm or less and an aspect ratio of 30 or more. The ferrite film is arranged or provided in the vicinity of an antenna conductor of a radio frequency identification tag. The ferrite film may be in direct contact with the antenna conductor.
