Using the highly precise full potential linearized augmented plane wave method, we determined atomic structure and the magnetostriction of Fe100-xGax with x<19%. It is demonstrated that the extraordinary enhancement of magnetostrictive coefficient of Fe100-xGax at low concentration stems from intrinsic electronic origins. Moreover, we recognized the potential of using a rigid band model for the prediction of magnetostriction of intermetallic alloys, through studies of ternary alloys with Zn substitution into Fe87.5Ga12.5.
