Title:
MAGNETIC BASE MATERIAL, LAMINATE FROM MAGNETIC BASE MATERIAL AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/060175
Kind Code:
A1
Abstract:
A method for producing a magnetic material of an amorphous metal thin belt, a magnetic base material having an amorphous metal thin belt and, provided thereon, a heat-resistant resin, or, a laminate therefrom, which comprises subjecting an amorphous metal thin belt containing Fe and Co as main components and being represented by the general formula: (Co(1-c)Fec)100-a-bXaYb wherein X represents at least one element selected from among Si, B, C and Ge, Y represents at least one element selected from among Zr, Nb, Ti, Hf, Ta, W, Cr, Mo, V, Ni, P, Al, Pt, Rh, Ru, Sn, Sb, Cu, Mn and rare earth elements, c, a and b satisfy 0 ≤ c ≤ 1.0, 10 < a ≤ 35, 0 ≤ b ≤ 30, respectively, and a and b represent an atomic %, or the base material, or the laminate, to a heat treatment under pressure. The base material and the laminate combines good magnetic characteristics, good mechanical properties and further good processability, and thus can be advantageously used for an antenna, which is an element for converting a radio wave to an electric signal, and a rotor and a stator of a motor.
