Features of the Implementation of the Vegard’s Law in Thin Films of Rare Earth Elements Compounds

Abstract:

In this work, the fulfillment of Vegard's law in thin polycrystalline films Sm_1-xGd_xS and Sm_1-xEu_xS, obtained by the method of explosive evaporation of the powder in vacuum, is investigated. It is shown that compliance with the Vegard law in the manufacture of thin-film structures based on Sm_1-xEu_xS solid solutions is possible only with the same technological parameters of film deposition, in particular, the substrate temperature. In the case of the Sm_1-xGd_xS solid solutions, the law is observed only in the metal phase of the solid solutions, with x> 0.12.
