Были исследованы зависимости фазового состава, морфологии и магнитных свойств наночастиц от их химического состава и условий проведения синте-за. С ростом температуры и продолжительности синтеза наблюдается повышение степени закристаллизованности и размеров частиц. При этом также повышаются значения намагниченности насыщения наночастиц за счет перераспределения катионов между подрешетками шпинельной структуры, сопровождающегося уменьшением степени об-ращенности. Для метода распылительного пиролиза зависимость удельной  намагниченности от состава феррита выражена слабо, в то время в случае нитрат-цитратного метода и метода соосаждения эта зависимость проходит через максимум. Наибольшее значение удельной намагниченности (30 А·м2·кг-1) соответствует образцу Mg0,5Zn0,5Fe2O4, полученному нитрат-цитратным методом.</p></abstract><trans-abstract xml:lang="en"><p>Superparamagnetic ferrite nanoparticles in the system of MgxZn1–xFe2O4 (х = 0.25; 0.5; 0.7) have been prepared by coprecipitation, spray pyrolysis and the nitrate-citrate approach. The dependence of the phase composition, morphology and magneticproperties of the nanoparticles on their chemical composition and synthesis conditions have been studied. The crystallinity degree and particle size tend to increase with the increase of the synthesis temperature and duration. The saturation magnetization of the nanoparticles increase as well due to cation redistribution between spinel structure sublattices, which is accompanied by reduction of the inversion degree. In the case of spray pyrolysis method, the correlation between saturation magnetization and ferrite composition is weak, while for coprecipitation and the nitrate-citrate approach it goes through a maximum. The highest saturation magnetization of 30 а∙m2∙kg–1 relates to  kg0,5Zn0,5Fe2O4 sample obtained by the nitrate-citrate approach.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитные наночастицы</kwd><kwd>магний-цинковый феррит</kwd><kwd>степень обращенности</kwd><kwd>пиролиз</kwd><kwd>соосаж- дение</kwd><kwd>нитрат-цитратный метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetic nanoparticles</kwd><kwd>magnesium-zinc ferrite</kwd><kwd>inversion degree</kwd><kwd>pyrolysis</kwd><kwd>coprecipitation</kwd><kwd>nitrate-citrate approach</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Разработка систем доставки лекарственных средств с применением микро- и наночастиц / А.
