“…Recently, much studies have been produced to study the electrical transport characteristics (TCR) of perovskite-structured oxides prepared using adopting conventional sol-gel technology. [4][5][6][7][8] The doped manganese oxide has many unique properties, such as phase separation, colossal magnetoresistance, the coexistence of diverse ordering types, etc. Electrical transport characteristics and magnetic properties are widely investigated for divalent alkaline-doped manganites.…”

Optical, magnetoresistance, and thermoelectric properties of La1−xKxMnO3 (x = 0.05, 0.15, and 0.25) compounds have been investigated. The crystallography demonstrates that the samples x = 0.05 and 0.15 are a single‐phase rhombohedral () structure, while x = 0.25 is near to a single rhombohedral phase with a minor amount of Mn3O4 (with a ratio of ≈2%). The optical properties manifest that the reflectivity decreases slightly with increasing x‐doping, where the sample of x = 0.05 has the lowest reflection value, making it a promising material for photovoltaic applications. Electrical resistivity measurements show that the samples have a metal–semiconductor transition, and the transition temperature Tms decreases with the K content. The thermoelectric data show a remarkable coincidence behavior of the ρ–T relationship, which has a peak at a transition temperature (TS). Magnetic susceptibility data show that the samples undergo ferro‐paramagnetic transition at a certain temperature (Curie temperature).
