The Mössbauer spectroscopy data on the 119Sn, 121Sb and 125Te isotopes have showed that the structure of germanium atoms local surrounding changes as a result of Ge2Sb2Te5 amorphous films crystallization (tetrahedral symmetry changes to octahedral), while the environment of antimony and tellurium atoms does not change, and for antimony atoms it is close to that in the Sb2Te3 compound.
