Magnetostrictive member, method of manufacturing magnetostrictive member, and evaluation method of magnetostrictive member

摘要

Problem to be solved: to provide a magnetostrictive member and a magnetostrictive member having a small amount of parallel magnetostriction and little variation in parallel magnetostriction between the members.A method of manufacturing a magnetostrictive member is a method of manufacturing a magnetostrictive member of a single crystal of an iron based alloy having magnetostrictive characteristics and having a longitudinal and short direction, and obtaining a magnetic domain structure of a single crystal and extending a magnetic domain Cutting the single crystal to be parallel to the longitudinal direction of the magnetostrictive member.Diagram
