Abstract
The present invention relates to a magnetic amorphous alloy sheet having an improved insulating property and improved corrosion resistance. The present invention aims to provide a film which is used to cover the magnetic amorphous alloy sheet, thereby improving its corrosion resistance and increasing the layer insulation resistance, without impairing the magnetic properties. The film according to the present invention has a thickness of up to 1 .mu.m and comprises a chromium compound which comprises hydrated chromium oxide. The film may additionally comprises metallic chromium. The magnetic amorphous alloy according to the present invention is suitable for use as a transformer core achieving a high building factor.
