Title:
ANTENNA CORE AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2008/018179
Kind Code:
A1
Abstract:
An antenna core produced by shaping a soft magnetic metal powder with the use of a resin as a binder, wherein the soft magnetic metal powder is an amorphous soft magnetic metal powder, or nanocrystal-containing amorphous soft magnetic metal powder, of the general formula (1): (Fe1-x-yCoxNiy)100-a-b-cSiaBbMc and wherein the resin as a binder is a thermosetting resin. In the formula, M is at least one element selected from the group consisting of Nb, Mo, Zr, W, Ta, Hf, Ti, V, Cr, Mn, Y, Pd, Ru, Ga, Ge, C, P, Al, Cu, Au, Ag, Sn and Sb. Each of x and y is an atomic ratio and each of a, b and c an atomic %, satisfying the relationships: 0≤x≤1.0, 0≤y≤0.5, 0≤x+y≤1.0, 0≤a≤24, 1≤b≤30, 0≤c≤30 and 2≤a+b≤30.
