摘要：
The nuclear magnetic resonance (NMR) spectrum of mixed-valence quadrupole centers in antiferromagnets is considered. A mechanism is proposed for the nonuniform broadening of this spectrum. The effect stems from a nonuniform distribution of the net charge in the random crystal fields. The influence of the external electric field on the shape of the NMR spectral distribution is investigated.
