Metallic Glasses: Investigation of Electronic Structure and its Relationship to Physical Properties

摘要

This report summarizes the work which was completed during the first four years of the research program (October 1, 1979 to September 30, 1983). Included are: (1) a NMR and magnetic susceptibility study of several rapidly quenched Ni-Pd-P, Ni-Pt-P and Ni-P metallic glasses. (2) a magnetization study of the RE100-xAlx amorphous alloys (where RE is a rare earth element), (3) a NMR, magnetization and x-ray diffraction study of crystalline Fe3-xNixSi and Metglas 2605 CO (Fe67Co18B14Si1), (4) a NMR and magnetic susceptibility study of the Ca100-xAlx metallic glass system, (5) a magnetization study of some Co-Nb-B and Fe-Nb-B metallic glasses, (6) an EXAFS study of Metaglas 2605 CO and (7) a XANES study of the (Ni0.50Pt0.50)75P25 metallic glass system. In addition, this report described in complete detail the progress during the past year (October 1, 1983 to September 30, 1984) which includes: (1) a spin-echo NMR study of the atomic environment in the Fe100-xBx metallic glass system and (2) a low field magnetization study of the magnetic anisotropy in Metglas 2605 CO ribbons. Finally, this report describes the status of experiments currently in progress which includes: (1) optical properties of the Ni100-xPx metallic glasses and (2) Mossbauer study of the Metglas 2605 CO system.
