A brief review on the effect of preparation conditions on magnetic properties of some A2MMnO6 (A = La, Eu and Y; M = Mg, Co, Ni) type perovskites

In this article, structural and magnetic properties of a number of A(2)MMnO(6) (A = La, Eu and Y; M = Mg, Co, Ni) type perovskites prepared under different oxygen partial pressure are compared. The results indicated that both structure and magnetic properties of such materials are sensitive to preparation conditions, which in general is governed by the nature of transition metal ions as well as rare-earth ions. It was also pointed out that even though the deviation in structure is only marginal, they affect appreciably to their magnetic properties. Graphic SYNPOSIS Sensitivities of structure and magnetic properties A(2)MMnO(6) types of perovskites to the preparation conditions have been reviewed briefly. Although the deviation in structure is marginal, they affect appreciably to their magnetic properties. The observed magnetic properties of several A(2)MMnO(6) types materials prepared under different conditions are summarized in this article.
