Abstract
To demonstrate the potential of nuclear magnetic resonance (NMR) spectroscopy for investigating detailed structural properties in ferromagnetic materials, three different particle sized cobalt (Co) powders have been ball milled for 24Â h are accurately characterised by internal-field 59Co NMR. The 59Co NMR spectra show distinct resonance bands corresponding to the different Co sites, face-centred-cubic (fcc), hexagonal-close-packed (hcp) and stacking faults (sfs), in Co metal powders. The hcp+fccâhcp phase transition encouraged by ball-milling was observed and quantitative values for each Co environment were obtained.
