ARMORPHOUS MAGNETIC ALLOY AND THE MANUFACTURING METHOD THEROF OF FE-HF-B SYSTEM HAVING HIGH-PERMEABILITY AND LOW COERCIVE FORCE

摘要

The method comprises the steps of preparing alloy consisting of iron 78 to 85 atom percent, Hf 6 to 9 atom percent, and B 9 to 13 atom percent; cooling a solution of the alloy; heating solution; and again cooling the solution.
