Rigid band model for prediction of magnetostriction of iron-gallium alloys

摘要

Using the highly precise full potential linearized augmented plane wave method, we determinednatomic structure and the magnetostriction of Fe100−xGax with xu000119%. It is demonstrated that thenextraordinary enhancement of magnetostrictive coefficient of Fe100−xGax at low concentration stemsnfrom intrinsic electronic origins. Moreover, we recognized the potential of using a rigid band modelnfor the prediction of magnetostriction of intermetallic alloys, through studies of ternary alloys withnZn substitution into Fe87.5Ga12.5.
