“…Rare-earth-based mixed valent perovskite manganites are well known for their thermopower and magnetoresistance properties. Half-doped Nd-Ca-based manganite Nd 0.5 Ca 0.5 MnO 3 is an interesting compound due to its exciting electric and magnetic properties [5][6][7] and is seldom studied for its thermopower properties. The equal concentration of Mn 3+ and Mn 4+ may give exciting MR properties for this compound.…”

Nd-Ca-based manganite Nd0.5Ca0.5MnO3 and 10% Ti-doped manganite Nd0.5Ca0.5Ti0.1Mn0.9O3 denoted by N and N0.1, respectively, were prepared using solid-state reaction method. Resistivity gets increased for the Ti-doped sample. The parent compound N has remarkably high magnetoresistance. The highest value of Seebeck coefficient for N is -97 μVK-1 at 143 K and for N0.1 is -207 μVK-1 at 203 K. Variable range hopping mechanism successfully explains the high temperature resistivity and thermopower data. Keywords: magnetoresistance, thermoelectric power, rare-earth based manganites, manganites.

Herein, the impact of exposing the perovskite compound Pr0.5Sr0.5MnO3 to oxygen plasma is explored by comparing the structural and transport properties of the exposed samples to those of the unexposed ones. The Pr is oxidized to PrO2 in the investigated samples due to plasma exposure. The alterations in the transport properties can be linked to the changes in MnOMn bond angle and MnO bond length due to plasma exposure, as indicated by X‐ray diffraction analysis. Additionally, exposure to oxygen plasma increases the conductivity by incorporating oxygen into the exposed samples, making them oxygen‐rich. Detailed analysis of the resistivity and thermoelectric power data indicates that small polarons are responsible for conduction at high temperatures, while at low temperatures, variable range polarons take over. The negative value of the thermopower at all temperatures proclaims that the electrons behave as the dominant charge carriers.
