摘要：

The Sm-147 Sm and Sm-149 NMR spin echo spectra of Sm2Fe17Nx (x=0, 0.4, 1.2, 2) series at 4.2 K are presented. The observed quadrupole septets are assigned to the 6c site of Sm with a different number of neighbouring N atoms. From the quadrupole splittings the values of the lattice contribution to the electric field gradient are obtained. On this basis the values of the crystal electric field coefficient A2(0) for different numbers of N neighbours are derived.
