Magnetic ground state of LBaCo2O5.5/5.44 cobalt oxides -: art. no. 134408

The magnetic properties of LBaCo2O5+gamma cobalt oxides with different types of oxygen ions ordering within [LO gamma] layers are discussed. Symmetry arguments are used to analyze the models of the magnetic ground state proposed for these compounds. By postulating the ordering between octahedraly coordinated cobalt ions in different spin states the magnetic structures explaining a variety of observed experimental data and consisting with the symmetry analysis are presented.
