A complicated spin-echo spectrum was observed for 209Bi nuclei in a ferroelectric antiferromagnet BiFeO3 in zero external field. This spectrum is the first example of nuclear quadrupole resonance of a system of diamagnetic atoms in a hyperfine magnet

By analyzing the NMR line shape, the transformation of a spatially spin-modulated magnetic structure in BiFeO3 into an ordinary spatially uniform structure of the LaFeO3 orthoferrite in Bi1−x LaxFeO3 solid solutions is studied. The measurements are

The 57Fe NMR spectra of the 57Fe-enriched (95.43%) ceramics of a ferroelectric antiferromagnet BiFeO3 with a spatially modulated magnetic structure have been studied. It is established that a cycloidal spin modulation in BiFeO3 causes a spatial modul

Spin-lattice (T 1) and spin-spin (T 2) relaxation times of 57Fe nuclei in the single-crystal NiFe2O4 and CoFe2O4 ferrites containing Fe2+ ions have been studied in the temperature range of 4.2–100 K by a spin-echo technique. The peaks of relaxation

The 57 Fe spin echo spectra were studied in local magnetic fields of a BiFeO3 ferroelectric antiferromagnet over the temperature range 77–304 K. The line shape analysis confirmed the presence of a spatially modulated, incommensurate cycloidal spin

Within the framework of the theory, specially developed for orthoferrites, the experimental results of NMR studies on Fe57 nuclei in domain walls of YFeO3 and LuFeO3 crystals are analysed. It is shown that the origin of two peaks in the wall NMR spec
