摘要: Abstract In addition to the known diffraction techniques, field-ion microscopy with atom probe is well established for determining long-range order parameter. The site occupation probabilities of chemical species on different sublattices may be estimated from experimental profiles. However, this evaluation method demands that superstructure planes identified unequivocally data. This condition not fulfilled in all cases. We propose a new analytical which need met.
