In this work the nanoscale characterization of chalcogenide glasses containing metals of As2Se3-Ag/AgI, As2S3-Ag/AgI, As2Se3:Bi, As2Se3-Bi2Se3 systems is carried out. The correlations on the atomic species level are established for the samples of As2Se3-Ag/AgI and As2S3-Ag/AgI systems with using magnetic suscpetibility measurement technique. The concentration of magnetic-ordered clusters (Ncl) and papamagnetic centers per cluster (N0) is estimated. The correlations on the void species level are established for the samples of As2Se3:Bi and As2Se3-Bi2Se3 systems (or (As1?xBix)2Se3) with using load-dependent microhardness measurement technique (indentation size effect). The dynamical effect of 109Ag NMR spectra for the glass (As2S3)65(AgI)35 with increasing temperature in the investigated temperature range 295-415 K is detected. Based on the combination of high energy synchrotron X-ray diffraction, extended X-ray absorption fine structure (EXAFS), reverse Monte-Carlo (RMC) simulation of diffraction data, high resolution Raman spectroscopy and ab-initio or DFT calculations the features of short and medium range order of chalcohalide glasses containing metals on the basis of Ge-In-S-AgI system is estimated for the investigated compounds 50GeS2-20In2S3-30AgI, 60GeS2-20In2S3-20AgI and 65GeS2-20In2S3-15AgI.
