The increasing monovalent sodium changes gradually the magnetic ordering from the layered type antiferromagnetism through spin-canted arrangement to the pure ferromagnetism with T_c÷125K.Pr_0.8Na_0.2MnO₃ exhibits a commensurate charge and orbit ordering of the Mn³⁺/Mn⁴⁺(1:1) kind below tě=215K, followed with a transition to the antiferromagnetic arrangement of pseudoCE type at Tn=175K.
