Исследуемые кристаллы были выращены методом Бриджмена из расплава, содержащего сульфид свинца, сульфид серебра или меди, гадолиний и серу (использованную для обеспечения стехиометрии). Исследования выполнены в диапазоне частот 9320÷9340 МГц при температурах 4, 2, 77 и 300 К. Установлено, что в исследуемых образцах примеси серебра и меди не создают значительных искажений структуры базового кристалла PbS, но существенно влияют на концентрацию свободных носителей. Анализ полученных данных о концентрационных и температурных зависимостях параметров спинового гамильтониана зондовых центров Gd3+ привел к выводу об акцепторном характере примесей серебра и меди в кристалле PbS, а также позволил определить их растворимость и описать индуцированные ими искажения структуры базового кристалла.</p></abstract><trans-abstract xml:lang="en"><p>Concentration and temperature dependences of parameters of the EPR spectra of Gd3+ centers introduced into the Pb1-xAgxS and Pb1-xCuxS thermoelectric semiconductor crystals (0 ≤ x ≤ 0,011) were investigated by means of EPR method. The crystals under investigation were grown from the melt containing lead sulfide, silver (or copper) sulfide, gadolinium and sulfur (the latter was used to provide stoichiometry). The investigations were performed in the 9320÷9340 MHz frequency range at temperatures of 4.2, 77, and 300 K. It was established that in the samples studied the silver and copper impurities did not create significant distortions in the structure of the base PbS crystal, but significantly affected the concentration of free carriers. Analysis of the obtained data on the concentration and temperature dependences of the spin-Hamiltonian parameters of the Gd3+ probe centers leads to the conclusion that silver and copper in the PbS crystal are acceptor like impurities, and also to determine their solubility and describe the distortions induced by them in the structure of the base crystal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>PbS</kwd><kwd>акцепторная примесь</kwd><kwd>серебро</kwd><kwd>медь</kwd><kwd>ЭПР</kwd><kwd>парамагнитный зонд</kwd><kwd>гадолиний</kwd><kwd>деформация решетки</kwd><kwd>свободные электроны</kwd><kwd>дырки</kwd><kwd>сдвиг Найта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PbS</kwd><kwd>acceptor like impurity</kwd><kwd>silver</kwd><kwd>copper</kwd><kwd>EPR</kwd><kwd>paramagnetic probe center</kwd><kwd>gadolinium</kwd><kwd>crystal lattice distortion</kwd><kwd>free carriers</kwd><kwd>EPR Knight shift</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">Jensen K.M.O., Bozin E.S., Malliakas C.D., Stone M.B., Lumsden M.D., Kanatzidis M.G., Shapiro S.M., Billinge S.J.L.
