Oxygen Plasma‐Induced Modification of Structural and Electrical Properties of Pr0.5Sr0.5MnO3 Manganites

physica status solidi (a), Volume 221, Issue 20, October 2024.
Plasma exposure enhances the oxygen content in the sample and changes the MnO bond length by increasing the MnOMn bond angle. This affects the electronic bandwidth and boosts the conductivity of the sample and trims down the absolute value of the Seebeck coefficient.
