Abstract

In this study, the manganites Nd0.5Ca0.5MnO3 , 0.5 Ca 0.5 MnO 3 , Nd 0.5 Sr 0.5 MnO 3, and Pr0.5Ca0.5MnO3 0.5 Ca 0.5 MnO 3 were investigated using infrared spectroscopy. The experiments were conducted under standard conditions at room temperature, and the infrared spectra of the compounds were analyzed within the wavenumber range of 400-4000 cm-1 . The observed frequencies primarily correspond to the Mn-O-Mn metal-oxygen bonds that form the MnO6 6 octahedron. Additionally, in the Nd0.5Ca0.5MnO3 0.5 Ca 0.5 MnO 3 and Pr0.5Ca0.5MnO3 0.5 Ca 0.5 MnO 3 compounds containing calcium, extra frequencies corresponding to Ca-O bonds were also detected.
