Установлено, что линии ЭПР имеют лоренцеву форму. Обнаружено, что в парамагнитной фазе с понижением температуры в области 6.8—60 К ширина резонансной линии ∆H сильно увеличивается и наблюдается сдвиг g-фактора, величина которого пропорциональна ширине линии ∆g(T) ∼ ∆H(T). Время релаксации ~10–10 с возрастает с повышением температуры.</p></abstract><trans-abstract xml:lang="en"><p>The features of the spectra of electron paramagnetic resonance (EPR) of MnIn2S4 single crystals at different temperatures are studied. It is established that EPR lines have a Lorentz shape. It is found that in the paramagnetic phase with a temperature decrease in the region of 6.8–60 K there is a strong increase in the range of resonance line ∆H and a shift in g-factor is observed, the values of which determine the proportional width of line ∆g(T) ∼ ∆H(T). The relaxation time is ~10–10 s and increases with increasing temperature.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>MnIn2S4</kwd><kwd>монокристалл</kwd><kwd>электронный парамагнитный резонанс</kwd><kwd>лоренцева линия</kwd><kwd>спин-спиновая релаксация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MnIn2S4</kwd><kwd>single crystal</kwd><kwd>electron paramagnetic resonance</kwd><kwd>Lorentz line</kwd><kwd>spin-spin relaxation</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">I.
