Abstract

PURPOSE:To easily enable to reduce iron-loss of a thin band by a method wherein a shaped fault is formed on the surface of a thin band and in an inner part of a noncrystal magnetic alloy. CONSTITUTION:A shaped fault such as a scratch and a pin hole are intentinally formed on the surface of a thin band or at the inner face of a noncrystal magnetic alloy thin band, and a size of magnetic domain is made small. For example, a smelted alloy having a composition of Fe78Si10B12 which is smelted from a nozzle 1 is made in contact and smelted with a copper roll 3 having a horizontal scar 5 and the horizontal scar is reproduced to an alloy ribbon 4 and then, it is precessed in annealing. By performing in this way, a iron loss of a noncrystal magnetic alloy thin band can be easily reduced.
