摘要：
Structural and magnetic properties of bulk amorphous alloys Fe74Al4Ga2P12B4Si4 (A), Fe76Al4P12B4Si4 (B), Fe80P12B4Si4 (C) and Fe74Al2Ga2P9B4Si8 (D) fabricated by a single-roller melt-spinning method were studied using X-ray diffraction (XRD), differential scanning calorimetry (DSC), magnetic measurements and Mossbauer spectroscopy (MS). The supercooled liquid region up to 45 K was determined from the DSC spectra. Magnetic and MS measurements revealed strong ferromagnetic ordering in the ribbons. XRD and MS were used to recognise the phases formed during annealing of the alloys. The average magnetisation became more random after annealing of samples A and B, while for the ribbons C and D an in-plane orientation of magnetisation was found. (C) 2002 Elsevier Science B.V.
