The heterostructure consists of nanometer-thick layers of Bi<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub> (BiIG) iron garnet and Gd<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> (GGG) paramagnetic garnet synthesized on SiO<sub>2</sub> quartz substrate. It is shown that a magnetic compensation point arises in the BiIG layer due to ion diffusion at the BiIG/GGG interface. The specific features of diamagnetic transitions, caused by the presence of Fe<sup>3+</sup> ions in different sublattices of the iron garnet and responsible for magneto-optical effects, are investigated around the magnetic compensation point. A sharp change in the energy of diamagnetic transitions is observed across the compensation point.</p></abstract><trans-abstract xml:lang="ru"><p>Приведены результаты исследования эффекта Фарадея и магнитного циркулярного дихроизма в гетероструктуре BiIG/GGG/SiO2, состоящей из слоев нанометровых толщин феррита-граната Bi3Fe5O12 (BiIG) и парамагнитного граната Gd3Ga5O12 (GGG), синтезированных на кварцевой подложке SiO2. Показано, что из-за диффузии ионов на интерфейсе BiIG/GGG в слое BiIG возникает точка компенсации магнитного момента ферримагнетика. Исследованы особенности диамагнитных переходов, обусловленных нахождением ионов Fe3+ в различные подрешетки феррита-граната и ответственных за магнитооптические эффекты, в окрестности точки компенсации магнитного момента. Обнаружено скачкообразное изменение энергии диамагнитных переходов при переходе через точку компенсации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>iron garnet</kwd><kwd>heterostructure</kwd><kwd>Faraday effect</kwd><kwd>magnetic circular dichroism</kwd><kwd>diamagnetic transitions</kwd><kwd>magnetic compensation point</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>феррит-гранат</kwd><kwd>гетероструктура</kwd><kwd>эффект Фарадея</kwd><kwd>магнитный циркулярный дихроизм</kwd><kwd>диамагнитные переходы</kwd><kwd>компенсация магнитного момента</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zvezdin A.K., Kotov V.A.
