Notes:
The magnetic properties of iron atoms implanted into a sapphire crystal at a dose from 4×1016 to 1×1017 Fe/cm2 were investigated using conversion electron Mössbauer spectroscopy at low temperature. It was confirmed that the components in the Mössbauer spectra which have been assigned to the Fe4+ state so far by other researchers are caused by fine particles of metallic iron, and about 75% of the implanted iron atoms stabilize in the form of fine particles of α iron at high implantation dose. Growth of the fine particles was simulated with a computer, and the expected Mössbauer spectra were calculated considering the influence of the nearest neighbors and next-nearest neighbors on the magnetic hyperfine field of the iron atoms. The simulated spectra agrees well with the experimentally observed spectra on the whole. © 1998 American Institute of Physics.
