NANOPERM-type alloys with nominal compositions of (Fe{sub 1-x}Co{sub x}){sub 76}Mo{sub 8}Cu{sub 1}B{sub 15}(x = 0 and 0.5) were prepared by a single-roller melt-spinning technique. Temperature evolution of the as-quenched ribbons during constant-rate heating (10 degree sign C/min) was continuously followed using a high-energy (88 keV) X-ray diffraction (XRD), performed on the ID11 undulator beamline at the ESRF (Grenoble, France). Moessbauer spectroscopy and XRD confirm an amorphous nature of the melt-spun ribbons. Furthermore, Moessbauer spectroscopy reveals a significant change of magnetic state of the as-quenched precursors when substituting Fe by Co (x 0.5). Analyzing a series of XRD patterns in a reciprocal space yields a thermal expansion of the amorphous alloys providing an insight about the thermally activated effects such as relaxation and crystallization.
