Local structure and magnetic properties of Mn3+–O–Fe3+ superexchange interaction in an oxygen-vacant perovskite: Experimental and theoretical study
(Elsevier Science, 2019-01)
In this work we report an experimental and theoretical study on the local structure and magnetic properties of Mn3+–O–Fe3+ superexchange interaction for an oxygen-vacant perovskite PrBaMnFeO5+ δ with δ ∼ 0.5. Structural ...
Multiferroicity and structural anomalies in Quadruple Perovskite Manganites: case study (A)Mn7O12, A = Na and La
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-01-15)
In this work we study the quadruple perovskite structure manganese oxides NaMn7O12 and LaMn7O12 under the point of view of multiferroicity, magnetoelectric coupling, and also structure anomalies on NaMn7O12. These studies ...
The BCL method for DSSC: basis and applications
(MDPI, 2022)
In this work, a comprehensive view of the route that led to the construction of a theoretical approach to the functioning of DSSC is presented. The model was developed based on the theoretical interpretation of experimental ...
