Abstract
An optical spectroscopic study of quasi-Haldane chain nickelate Sm\(_{2}\)BaNiO\(_{5}\) is presented. A temperature-dependent splitting of the ground-state Kramers doublet of the Sm\(^{3+}\) ion due to an antiferromagnetic ordering at \(T_{N}\) = 55 K has been obtained experimentally and used to calculate the Schottky-type anomaly in magnetic susceptibility. The value of the magnetic moment of Sm\(^{3+}\) ion at zero temperature has been estimated within the model of the ground doublet. One-dimensional magnetic behavior of the nickel subsystem is emphasized.
