Description

NMR was measured on Mn55 nuclei in CsMnBr3, RbMnBr3, CsMnI3 quasi-one-dimensional antiferromagnetics within up to 8 T magnetic fields and within 1.3-4.2 K temperature range. On the ground of the obtained data on hyperfine fields the average moments of magnetic sublattices and their field dependences turned to be rather strong and various ones for Mn2+ magnetically nonequivalent ions were determined. As a result magnetization value of certain sublattices within ∼ 8 T external magnetic field differ by over 5%. The obtained results qualitatively correspond to the theory of suppression of quantum fluctuations by magnetic field
