Abstract

PURPOSE:To carry out demagnetization treatment of an Alnico type magnet in a short time in an AC alternating magentic field without requiring nay demagnetizationtreatment unit by giving desired magenetic anisotropy in a predetermined temp. range to the magnet heated to the soln. heat treatment temp., followed by damage demagnetic demagnetization treatment in a lower predetermined temp. range.
