• We report on the effect of carbon implantation on the structural, electronic, and magnetic properties of Fe<inf>93</inf>Zr<inf>7</inf>(FeZr) amorphous films. Extended X-ray absorption fine structure measurements on (FeZr)<inf>100-x</inf>C<inf>x</inf>(x = 0, 5.5, and 11) indicate the incorporation of carbon in the FeZr matrix, with an increase of the Fe--Fe distance by implanting carbon. X-ray photoelectron spectroscopy measurements reveal the creation of Fe--C bonds after implantation. A significant enhancement of the Curie temperature and decrease of the coercivity are observed in the carbon-implanted films. Moreover, the non collinear ferromagnetism of the as-grown FeZr film diminishes upon carbon implantation.
