Review of structural and magnetic properties in substituted charge ordered monovalent and divalent doped manganites / Nurul Najwa Abd Aziz

Perovskite manganites refer to a family of manganese compounds with a general composition of AMnO3, where A = La, Bi, Nd, Pr, which crystallize in the perovskite structure named. This paper provides an overview of the state of the art in studies on fabrication, structural characterization, magnetic properties, and applications of monovalent and divalent doped charge ordered manganite. A throughout understanding of the effect of K+ and Ba2+ substitution at A site while Cr3+ and Ni2+ substitution at B site in monovalent-doped and divalent-doped charge ordered manganite on magnetic properties. Firstly, a review begins with a brief introduction to the history of research and unusual findings in charge ordered manganite. In the second part, the different methods used for the fabrication of charge ordered manganite are summarized. Next, in the third part is the structural characterization of A site and B site are examined in more depth. Following that, the magnetic properties of A site and B site substitution on monovalent and divalent charge ordered manganites are reviewed more detail in fourth part. Based on previous studies, it has been proposed that the disorder induced by doping at both site and the magnetic exchange interaction between both site with doped ions play a key role in explaining the magnetic properties. In addition, the potential applications of charge ordered manganite are highlighted in the following parts. Finally, this review concludes with some perspectives and challenges for future research of charge ordered manganite. As conclusion, this review is more focused on structural and magnetic properties in substituted charge ordered monovalent and divalent doped manganites.
