X-ray and NMR investigations of cobalt

Abstract
X-ray diffraction and zero-field NMR spectra were studied for powdered and bulk polycrystalline and single-crystal specimens of cobalt. The nature of the h.c.p.-f.c.c. phase transition was studied. It is shown that the two stacking fault NMR lines are both due to deformation faults in h.c.p. regions.
