The increasing monovalent sodium changes gradually the magnetic ordering from the layered type antiferromagnetism through spin-canted arrangement to the pure ferromagnetism with Tc÷125K.Pr0.8Na0.2MnO3 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.
