Magnetostriction and structural characterization of fe ga alloys

Abstract

Magnetostrictive materials are one of the classifications that have been able to quantify and categorize varying levels of smartness or intelligence in systems. The contraction of a ferromagnetic material that occurs as a result of an applied magnetic field is referred to as magnetostriction. During the process of researching a variety of types of iron, ferrous steels, and nickel, Ames Prescott Joule conducted an experiment in which he discovered this phenomenon. The fact that increasing magnetostriction by up to 2000 ppm by alloying rare earth elements like terbium and dysprosium with iron (Terfenol-D) may be accomplished is something that was previously unknown until it was discovered. Although this material has a significant magnetostriction, which makes it a potential alternative for actuation and sensing, its usability in many applications is limited due to the fact that it is extremely fragile. newline
