Abstract
Official abstract text for this publication.
A iron-based amorphous alloy thin strip having a chemical composition represented by a chemical formula of Fe x B y Si z (wherein x is 78-83 at %, y is 8-15 at % and z is 6-13 at %), wherein the number of air pockets at a surface contacting with a cooling roll is not more than 8 pockets/mm 2 and an average length in a circumferential direction of the roll is not more than 0.5 mm.
