Abstract:
1. A magnetic alloy having a composition represented by the following general formula (1): wherein x and y are numbers meeting the conditions of 1.2≦x≦1.6, and 10≦y≦20, wherein said magnetic alloy has a structure containing crystal grains having an average diameter of 60 nm or less which is dispersed in a proportion of 30% or more by volume in an amorphous matrix, and a saturation magnetic flux density of 1.7 T or more and a coercivity of 24 A/m or less, and wherein said magnetic alloy is obtained by heat-treating a fine crystalline alloy having a structure in which crystal grains having an average diameter of 30 nm or less are dispersed in an amorphous phase in a proportion of more than 0% by volume and 30% by volume or less.
