Correlation between orbital structure and magnetic ordering in layered manganites is examined. A level separation between the 3d3z2-r2 and 3dx2-y2 orbitals in a Mn ion is calculated in the ionic model for a large number of the compounds. It is found that the relative stability of the orbitals dominates the magnetic transition temperatures as well as the magnetic structures at zero temperature. A mechanism of the correlation between orbital and magnetism is explained by a theory based on the model with the two eg orbitals under strong electron correlation.
