Аннотация
The spectral distribution of NMR frequencies of 3d-ions of a mixed valence is investigated in impurity complexes of a magnetically ordered crystal. It is shown that peculiarities of these spectra are due to the effects of spin density averaging. The effect of electron exchange on the NMR spectrum of chromium ions in Cd1–xInxCr2Se4 is studied experimentally, and the obtained results are interpreted by using the developed theory.
