By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn$_3$)Mn$_4$O$_{12}$, where a peculiar quadruple perovskite structure with no oxygen disorder stabilizes a nearl

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) 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
