Abstract

By the sol-gel method of autocombustionan initial oxide system was synthesized for a receipt a nanodispersed Yttrium Iron Garnet. It was set that forming of the monophase system Y3Fe5O12 begins at temperatures above 973 К in static air atmosphere. The crystalquasichemical formulas for Y3Fe5O12 are offered. Dependence of concentration of defects from a degree non-stoichiometry of oxygen is calculated. It was set that the formation of garnet structure needed oxygen atmosphere annealing. Partial pressure of oxygen determines the resulting structure defects.
