The transition of impurity iron atoms from a paramagnetic to a ferromagnetic state is described. It was found that the transition occurs at different concentrations of oxygen vacancies for two crystallographically nonequivalent types of impurity iron atoms and is accompanied by a change in the charge state of the impurity.</p></abstract><trans-abstract xml:lang="ru"><p>Расчетами в приближении когерентного потенциала подтверждены современные представления о различных зарядовых, спиновых и магнитных состояниях примесных атомов железа, замещающих атомы индия, в оксиде (In<sub>0.95</sub>Fe<sub>0.05</sub>)<sub>2</sub>O<sub>3–δ </sub>при составах, нестехиометрических по кислороду (0 &lt; δ ≤ 0.09). Описан переход примесных атомов железа из парамагнитного в ферромагнитное состояние. Выяснено, что переход происходит при разных концентрациях кислородных вакансий для двух кристаллографически неэквивалентных типов примесных атомов железа и сопровождается изменением зарядового состояния примеси.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coherent potential approximation</kwd><kwd>electronic structure of indium (III) oxide</kwd><kwd>magnetic and charge states of impurity iron atoms</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>приближение когерентного потенциала</kwd><kwd>электронная структура оксида индия (III)</kwd><kwd>магнитные и зарядовые состояния примесных атомов железа</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Государственное задание Минобрнауки России для ИФМ УрО РАН</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Babu S.H., Kaleemulla S., Rao N.M., Krishnamoorthi C.
