摘要: The distribution of Ni in LaNiy Co1–yO3 solid solutions was examined by means EPR spectroscopy. For the assignment signals, La1–xSrx CoO3 oxides were used as reference for Co3+–Co4+ magnetic clusters. heated at 600 °C, spectra consist a signal due to clusters, while prepared 700 °C display an ferromagnetic coupled Co3+ and Co4+ impurity ions that do not form samples T > are “silent”. effect preparation method temperature on formation clusters is discussed.
