      abstract     = {Magnetostrictive materials transduce magnetic and
                      mechanical energies and when combinedwith piezoelectric
                      elements, evoke magnetoelectric transduction for
                      high-sensitivity magneticfield sensors and energy-efficient
                      beyond-CMOS technologies. The dearth of ductile,
                      rare-earth-free materials with high magnetostrictive
                      coefficients motivates the discovery ofsuperior materials.
                      Fe 1−x Ga x alloys are amongst the highest performing
                      rare-earth-freemagnetostrictive materials; however,
                      magnetostriction becomes sharply suppressed beyondx = $19\%$
                      due to the formation of a parasitic ordered intermetallic
                      phase. Here, we harnessepitaxy to extend the stability of
                      the BCC Fe 1−x Ga x alloy to gallium compositions as high
                      asx = $30\%$ and in so doing dramatically boost the
                      magnetostriction by as much as 10x relativeto the bulk and
                      2x larger than canonical rare-earth based magnetostrictors.
