Abstract:
Results of an experimental investigation of the peculiarities of phase transitions in iron compounds localized in natural low-dimensional systems (nanoclays) are reported. Conditions for observation of the $(I_c\overset{188 K}\longrightarrow I_h)$ phase transition by Mössbauer spectroscopy in thin films of ice adsorbed on the surface of typical clays are established for the first time. Data obtained by the proposed method for the geography of iron exchange complexes on aluminosilicate clay surface are presented.
