The main purpose of the research works was study of doping effect on physical properties of compounds and search of new thermoelectric and magnetic materials. For realization of this purpose were: the isothermal sections of the phase diagrams of the (Ce,Nd,Sm,Dy)-Cо-Sn, Dy-Ag-Sn, (Nd,Sm,Dy)-Ni-Sn, Hf-Cu-Sb, (Dy,Lu)-Cu-Sn, and Zr-Ni-Sb systems were plotted; the crystal structure of Zr3NiSb7, Dy2Ni7Sn3, R3Co4Sn13 (R=Pr,Nd), R3Ni8Sn4 (R=Sm,Gd), R3Ag4Sn4 (R=Y,Gd,Tb,Ho,Er), RAgSn2 (R=Y,Gd-Dy,Ho,Er), and R4Ni12Sn25 (R=Nd,Dy) ternary compounds were refined by X-ray methods; physical properties of Zr1-xDyxNiSn, ZrNiSn1-xInx, ZrNi1-хFeхSn, ZrNi1-xMnxSn, TiNiSn1-xInx, Ti1-хVхCoSb та SmCo9-xFexSi4 solid solutions were investigated; electronic structure of the RNi3Sn2 (R = Y, Gd) compounds and Zr1-xDyxNiSn, ZrNiSn1-xInx, ZrNi1-xMnxSn, TiNiSn1-xInx, Ti1-хVхCoSb related solid solutions alloys was calculated. The calculations of the elecytronic structure of the compounds with the MgAgAs ST confirm that they are semiconductors available to application as thermoelectric materials.5635
