摘要：

Annealing in argon of MnTiO3 impregnated with a SnCl4 solution leads to the distribution of Sn4+ ions over sites with different cationic environments in the surface layers of crystallites. The chemical behavior of Sn4+ ions emerging on the surface upon subsequent annealing in hydrogen depends on the tendency of the neighboring cations to retain the octahedral coordination by O2- anions. The absence of spin polarization of the Sn2+ cations formed on the surface shows that their specific valence state is stabilized by the nearby Ti4+ cations. © Allerton Press, Inc. 2007.
