• The number of the inequivalent octahedral sites on which Fe" ions are locatedand the values of the anisotropic internal fields of the ions were determined inthe preceding paper. From these results and under the several assumptions,the electron ordering schemes on the (001) planes were determined completely.There remains some ambiguity on the way of piling up these c-planes along thec-axis. The proposed electron ordering scheme is as follows. Along the a-axisa pair of Fe" ions and a pair of Fe" ions line up alternately. Along the Z>-axisa group of three Fe" ions and one Fe" ion or a group of three Fe" tons andone Fe" ion line up alternately. This electron ordering may be caused by thepairing of Fe" ions along the o-axis as well as the short range ordering due to theelectrostatic energy. The new model is quite promising but the NMR study atthe present stage still cannot eliminate other electron orderings, e.g., Fe" ionand Fe" ion align alternately along the a- and />-axes.
