Effect of Co‐Doping on the Structural and Dielectric Properties of La0.8K0.2MnO3 Perovskite

“…Moreover, it was reported that the substitution of a monovalent cation has twice effect on the valence state of manganese, which has a great effect on the phase transition of manganites. [ 20 ]…”

“…Moreover, it was reported that the substitution of a monovalent cation has twice effect on the valence state of manganese, which has a great effect on the phase transition of manganites. [20] Furthermore, due to their valence difference, the monovalent ions convert twice more Mn 3þ ions than the divalent ions. In particular, potassium-doped lanthanum manganite results in a large number of charge carriers, which in turn enhances conductivity.…”

“…A detailed investigation showed that LaSrMnO 3 , doped by a monovalent alkali-metal ion (K þ1 ) at the A-site, achieved great transport properties along with appreciable magnetoresistance value. [20] Compared with A-site doping, the substitution of Mn-site (or B site) is more important. Recently, a growing research activity have been selected to study the effect of dopant type in the Mn-site by some transition elements, such as Ni, Co, Fe, and Cu, on the structural and dielectric properties of manganite.…”
