Rapidly quenched (Co95Fe5)1-xAlx ribbons are investigated by X‐ray diffraction, magnetization, and Mossbauer effect measurements. A single fcc phase is obtained for all ribbons x ⩽ 10 at.%. The lattice constant increases linearly with x and is discussed in connection with magnetic moment. The influence of Al substitution on both magnetization and Fe‐atom hyperfine field (H) is studied. At 296 K, the magnetization decreases linearly while H drops nonlinearly as x increases. Al substitution leads to substantial differences in iron hyperfine fields in bcc and fcc systems. Fe moment is perturbed differently by Al substitution in fcc (Co95Fe5)1-xAlx and bcc Fe–Al systems. |
