The nuclear magnetic resonance (NMR) method is used to study electronuclear interactions in the 57Fe and 69/71Ga nuclei in gallium-substituted thulium orthoferrite at temperatures corresponding to the beginning and end of the spin-flip phase transition Г2(GzFx) → Г4(GxFz). The values of indirect hyperfine fields are obtained for the first time on the 69/71Ga nuclei in orthoferrites. The obtained results are discussed.
