Abstract
A method for achieving a flat magnetization loop in cores, such as for use in inductive components, which are wound of amorphous ribbon includes the steps of subjecting the wound core to long-term heat treatment of more than 10 hours, and selecting the temperature during the heat treatment so low that less than half of the ribbon cross-section exhibits crystalline precipitations which occur during the heat treatment.
