Effects of Ni2+ and Cr3+ Substitution at Mn-Site on Structural and Electrical Resistivity of Charge Ordered Divalent-Doped Sm0.5Ca0.5MnO3 Manganite
Perovskite manganites (R1-xAxMnO3) are widely studied for their unique magneto-transport properties, especially the metal-insulator transitions. Sm0.5Ca0.5MnO3 is a prototypical half-doped manganite known for its strong charge-ordering (CO) behaviour and high CO temperature (TCO ≈ 270 K), which limits its practical app...
