Single-Crystal Magnetic Anisotropy and Magnetostriction Studies in Iron-Base Alloys

Abstract

Single crystals of a number of binary iron-base alloys were grown, fabricated, and tested for magnetic anisotropy (K1) and magnetostriction (λ100 and λ111). The additions made to iron included vanadium, molybdenum, germanium, chromium, titanium, and tin. The anisotropy of iron was lowered by the addition elements with the possible exception of tin. On the other hand, λ100 of iron was generally raised by these addition elements. Only titanium and tin lowered λ100; however, titanium had limited solublilty in iron and tin caused embrittlement.
