Review of structural and electrical properties in substituted charge ordered monovalent and divalent-doped manganites / Nur Anis Natasha Ahmad Rofie

Rare earth doping causes a change in the valence states of manganese, which plays a key role in the transport characteristics, hence rare earth-doped perovskite manganite oxides have substantially more diversified electrical properties than their parent perovskite manganite oxides. Thus, this paper reviews on the effect of substitution at A and B-sites on electrical properties in monovalent-doped and divalent-doped charge ordered manganites. This paper provides an overview of the state of the art in fabrication, structural characterization, electrical properties, and applications of charge ordered manganites. Our review first begins with a brief introduction of the research history and significant discoveries in charge ordered manganites. The second part summarizes the various approaches for fabricating charge ordered manganites. The structural characterization of the A and B-sites substitution in monovalent and divalent charge ordered manganites are reviewed in detail in the third part. Following that, in the fourth part, the electrical properties of the A and B-sites substitution in monovalent and divalent charge ordered manganites are thoroughly reviewed. Charge ordered manganites’ potential applications in the fields of magnetic memory devices, magnetic sensors and spintronic devices are highlighted in the following parts. Finally, this review concludes with some perspectives and challenges for charge ordered manganites future researchers in the final part.
