Tuning the microstructure and magnetocaloric properties of Na+-substituted La0.67Ca0.33−xNaxMnO3 porous nanospheres

Investigation of the impact of A-site cation disorder on the structure, magnetic properties, and magnetic entropy change of trisubstituted divalent ions in La0.7(Ba,Ca,Sr)0.3MnO3 manganite

“…48 Initially, similar O 1s spectra were observed for other perovskite manganites, with various interpretations and contradictions, referring to oxygen bonding with the various elements of the compound, defects and vacancies. [48][49][50][51][53][54][55][58][59][60][61] Based on several studies, the deconvolution of the O 1s spectra obtained for LBCS compounds segregates the contribution from the three different types of oxygen species as shown in Fig. 10.…”
