Abstract

The peculiarities of NMR spectral distribution of Jahn-Teller (JT) ions and mixed valence (MV) complexes in magnetically ordered crystals are investigated. The main attention is given to the mechanisms of nonuniform broadening of the NMR spectra and to the effects leading to the increase of spectral lines' intensities. The temperature and angular dependences of NMR spectrum of 3d-ions with two-fold degenerate ground state in magnetics with random crystal fields are analyzed. The obtained results are illustrated by the experimental data on the low- and high-temperature NMR spectra of Jahn-Teller ions (Mn³⁺, Cu²⁺, and Co²⁺) in magnetic crystals.
