Structural, morphological, magnetic and electrical properties of La_0.8Na_0.2-x □ _x MnO₃ (0.00 ≤ x ≤ 0.15) manganites.

ABSTRACT: La_0.8Na_0.2-x □ _x MnO₃ (0.00 ≤ x ≤ 0.15) manganites were successfully synthesized using the solid-state route. X-ray diffraction was performed to check the samples' purity and phase structure. Scanning electron microscopy analysis reveals a decrease in the average grain size with an increase in the deficiency amount. Analysis of the temperature dependence of magnetization proved the presence of ferromagnetic-paramagnetic transition in all the studied samples. The magnetization derivative (d² M/dT ²) curves demonstrated a decrease in the transition temperature with an increase in the deficiency amount. Such experimental observations can be correlated with bandwidth evolution, which affected d
