First principles investigations for the extraordinary magnetostrictive properties of Fe100-xGax alloys
Abstract
UC Irvine proposes to extend thierONR research program for the theoretical studies of structural and magnetostrictive properties of Galfenol and related alloys that have unusually strong magnetostriction and excellent mechanical properties. These materials are free of rare-earth elements and are thus sustainable for industrial and defense applications. New development and optimization of these alloys rely on clear fundamental understandings of their electronic and magnetic features. Through extensive density functionalca"lculations and molecular dynamics simulations, our research is able to (1) provide fundamental insights and (2) predict new ingredie"nts for better performance. Thereliability and applicability of our density functional approaches for studies of magnetostriction h"ave been well established in the last decade. With the continuing ONR support in the last two years, we have made more progresses in" identifying the key factors for the large magnetostriction of Galfenol and related alloys.
