摘要：

Murdochite-type (Mg6-xAlx)MnO8 (0 ≤ x ≤ 0.3) was synthesized at 1073 K using a solid state reaction. The cell constants of (Mg6-xAlx)MnO8 monotonously decrease with increasing x. From the results of the magnetic measurement, both low-spin and high-spin states of Mn3+ ions coexist. The binding energy of Mn 2p3/2 determined from XPS measurement is independent of the composition. But the full width at haft maximum (FWHM) of the Mn 2p3/2 peak increases with increasing x. The presence of both low-spin and high-spin slates of the Mn3+ ion causes an increase of the FWHM of the Mn 2p3/2 peak. © 1993 Academic Press, Inc.
