Solid solutions on the basis of bismuthides of rare earth elements of yttrium subgroup

The scientific based methods of synthesis of bismuthides Ln₅Bi₃ and solid solutions Gd_5-xLn_xBi₃ have been elaborated. The investigation of state diagrams of Gd₅Bi₃-Ln₅Bi₃ systems allowed to determine the regularity of their structure which reveals in formation of isostructural line of substitution of solid solutions Gd_5-xLn_xBi₃. The effective magnetic moments of ions of rare earth elements, Curie paramagnetic temperatures, conductivity character have been defined. The solid solutions Gd_5-xLn_xBi₃ with increased magnetic properties have been obtained.
