Document Type and Number:
Japanese Patent JP5445889
Kind Code:
B2
Abstract:
A magnetic alloy having a composition represented by the general formula of Fe 100-x-y Cu x B y (atomic %),wherein x and y are numbers meeting the conditions of 0.1 ¤ x ¤ 3, and 10 ¤ y ¤ 20, or the general formula of Fe 100-x-y-z Cu x B y X z (atomic %),wherein X is at least one element selected from the group consisting of Si, S, C, P, Al, Ge, Ga and Be, and x, y and z are numbers meeting the conditions of 0.1 ¤ x ¤ 3, 10 ¤ y ¤ 20, 0 < z ¤ 10, and 10 < y + z ¤ 24), the magnetic alloy having a structure containing crystal grains having an average diameter of 60 nm or less in an amorphous matrix, and a saturation magnetic flux density of 1.7 T or more.
