Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ЖЕЛЕЗО -- ЛИТИЙ -- ТВЕРДЫЕ РАСТВОРЫ -- МАГНИТНАЯ ВОСПРИИМЧИВОСТЬ -- ЯДЕРНЫЙ МАГНИТНЫЙ РЕЗОНАНС Аннотация: LiFexc1–xO2 solid solutions (0.005 < x < 0.10) were studied by the NMR and magnetic susceptibility methods. The anomalies of temperature and concentration dependences of magnetic susceptibility are accounted for by the contributions of single iron atoms and clusters containing iron, oxygen, and lithium atoms. According to the NMR spectroscopy data, lithium atoms also are in two states and enter the cluster composition Полный текст |
