Abstract
Contrary to the claim made by Rhyne and Fish, based on their small‐angle neutron scattering data, that amorphous (a‐) Fe91Zr9 does not exhibit long‐range ferromagnetism at any temperature but instead enters a spin‐glass state at temperatures as high as ∼210 K, our recent ac susceptibility data demonstrate that a long‐range ferromagnetic order is established in this alloy at Tc≂210 K. A host of other experimental observations on the same or nearby compositions in the a‐Fe90±xZr10∓x alloy series, available in the literature, are shown to provide firm support to our inference.
