The multiquantum spin-echo signals from Cu-63 and Cu-65 nuclei in both Sb-doped and undoped samples of CuCr2S4 have been found experimentally. An additional line has been found experimentally in the Cr-53 NMR spectrum of Sb-doped sample. The influence of lattice defects, which are S-vacations and Sb-dopents, are discussed to analyze the experimental data.
