NMR frequencies of domain walls in a (110) plate of yttrium iron garnet upon the magnetization in the $$[bar 110]$$ direction

Numerical methods have been used to study the shapes of NMR absorption lines of domain walls (DWs) in a (110) plate of yttrium iron garnet upon the magnetization along the ([bar 1 10]) direction. NMR spectra obtained from ⁵⁷Fe nuclei located in tetrahedral and octahedral positions in Bloch and Néel walls in a longitudinal and transverse radiofrequency fields have been studied. The dependences of the frequencies of the NMR absorption maxima of DWs on the magnitude of the applied magnetic field permit one to unambiguously determine the type of rotation of magnetization in the transition layer. It is shown that by changing the conditions of excitation of oscillations of the radiofrequency field, signals from nuclei located in various layers of the DW can be obtained.
