(Color online) (a) alloy system shown as a pseudoternary phase diagram with limiting compositions , , and . The set of melt-quenched compositions and their structure are indicated by the marks. (b) XRD pattern (Co ) of as-quenched ribbons with and . XRD pattern for in annealed state is shown with Miller indices of the -type structure. (c) HRTEM image of showing only amorphous contrast patterns (main panel). Inset (d) is an overview from conventional TEM; (e) is the diffraction pattern from a circular area of about diameter, showing no signs of crystalline reflections.
