Ab initio calculation of magnetic hyperfine interac-tion on 51V nuclei in pyrochlore Lu2V2O7 is performed. The comparative analysis of the calculated values and known experimental data is made. It is shown that the unrestricted Hartree–Fock method is most acceptable to descript the magnetic properties on the nucleus of ions as compared to the density functional theory method with the hybrid functionals B3LYP and PBE0.
