Nuclear magnetic resonance and dynamics of single-domainization of antiferromagnetic FeBO3 in a DC magnetic field

Experimental observations of the effect of domain structure on the NMR sign als of Fe-57 nuclei in ferric berate for three orientations of de (H) and a c (H-1) magnetic fields with respect to the basal plane are presented. The dependences of the intensities and resonance frequencies of NMR signals on the de magnetic field were studied. A theoretical explanation is suggested for the observed dependences. The effects are shown to depend on the specif ic features of the lamellar domain structure and weak ferromagnetism of fer ric berate.
