Description
Summary:In order to investigate the near neighbor atomic environment and, consequently, the relationship of such environments to the observed magnetoelastic properties, a spin-echo NMR study of the hyperfine field distributions in Metglas 2605 CO (Fe67Co18B14Si1) for various magnetic annealing treatments has been undertaken. Here, initial spectra for the 11B metalloid and 59Co transition metal nuclei, obtained at 4.2 °K and zero magnetic field, are presented along with supplementary magnetization and x-ray diffraction measurements. Upon annealing, a bcc α-Fe phase precipitates first, leaving a residual amorphous phase of lower Fe content. The appearance of such crystalline regions is accompanied by a strong reduction in the magnetomechanical coupling coefficient.
