В отожженных кристаллах ZrO2 стабилизированных только оксидом иттрия (2,8 % (мол.) Y2O3) установлено присутствие Zr3+ центров. При добавлении СeO2 к кристаллам ZrO2, помимо оксида иттрия, проявляется другой вид парамагнитных O–−центров. Для оценки концентрации ионов Ce3+ в кристаллах ЧСЦ зарегистрированы спектры ЭПР в присутствии эталона при температуре 7 К. Идентифицированы парамагнитные ионы Ce3+ и их относительное количество в кристаллах ЧСЦ до и после высокотемпературной термообработки. Показано, что проведенные в работе отжиги на воздухе, приводят к уменьшению концентрации ионов Ce3+ для всех составов, а также изменяют цвет кристаллов с красного на белый. В образце 2,0Y0,8CeZr после отжига количество парамагнитных ионов Ce3+ уменьшилось примерно в два раза. В образце с малым содержание церия (0,1 % (мол.)) после отжига парамагнитные центры от Ce3+ не регистрируются, что говорит о полном переходе Ce3+ в состояние Ce4+. Показано, что образованные парамагнитные центры церия, связаны сильными обменными взаимодействиями. Угловая зависимость ЭПР линий от парамагнитных катионов Ce3+ от приложенного внешнего магнитного поля не наблюдалась. Вероятной причиной отсутствия угловой зависимости является то, что примесные редкоземельные ионы расположены рядом друг с другом, образуя примесные кластеры с эффективным спином Seff = 1/2.</p></abstract><trans-abstract xml:lang="en"><p>The study of crystals of ZrO2 solid solutions (PSZ) stabilized with yttrium and cerium oxides was carried out by electron paramagnetic resonance (EPR) in the X and Q range. The presence of Zr3+ centers in annealed ZrO2 crystals stabilized only by yttrium oxide (2.8 mol.% Y2O3) is established. Another kind of paramagnetic O−centers appear when CeO2 is added to ZrO2 crystals in addition to yttrium oxide. To estimate the concentration of Ce3+ ions in PZS crystals, EPR spectra were recorded in the presence of a reference specimen at 7 K. Paramagnetic Ce3+ ions have been identified and their relative amounts in PSZ crystals before and after high−temperature heat treatment has been measured. The annealing in air leads to a decrease in the concentration of Ce3+ ions for all compositions and changes the color of the crystals from red to white. After annealing in the 2.0Y0.8Ce3Zr sample, the amount of paramagnetic Ce3+ ions decreased approximately twice. Paramagnetic centers from Ce3+ are not detected in a the sample with a low cerium content of 0.1 mol.% after annealing which indicates the complete transition of Ce3+ to the Ce4+ state. It is shown that the formed paramagnetic centers of cerium are bound by strong exchange interactions. No angular dependence of the EPR lines for the paramagnetic Ce3+ cations on the applied external magnetic field was observed. The probable reason for the absence of such angular dependence is that impurity rare−earth ions are located next to each other, forming impurity clusters with effective spin Seff = 1/2.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ЭПР</kwd><kwd>частично стабилизированый диоксид циркония</kwd></kwd-group><kwd-group xml:lang="en"><kwd>EPR</kwd><kwd>partially stabilized zirconia dioxide</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ № 16−02−00742а</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chan C.
