Abstract—Crystal chemical models are proposed for describing the regularities in the distributions of ions and
point defects in solid solutions of yttrium aluminum, yttrium gallium, and yttrium iron garnets. The concentra-
tion dependences of the distributions of ions and point defects in solid solutions are evaluated in terms of mul-
tidimensional nonlinear optimization. © 2003 MAIK “Nauka/Interperiodica”.
