Evaluation of the electronic, optical, thermoelectrical and magnetic properties of manganite perovskites via DFT calculations and critical exponent analysis

What is it about?

The results of DFT calculations demonstrated that La0.8Sr0.2- Mn0.8Co0.2O3 exhibited spin-dependent transport with a p-type semiconducting behaviour in one configuration and a metallic behaviour in the other. Optical analysis confirmed its high dielectric response and ultraviolet absorption. Thermoelectric investigations demonstrated a thermally activated carrier transport and a strong power factor at high temperatures. Critical exponent analysis revealed distinct magnetic behaviours, from short-range magnetic behaviour, to mixed short- and long-range interactions.
