Abstract: Cadmium ions (Cd2+) are similar to calcium ions (Ca2+) in size, whereas the Cd2+ ions tend to form covalent bonds with the neighboring anions because of the high electronegativity. The covalent Cd-O bonds affect other… read more here.

DOI: 10.1021/acs.inorgchem.9b02298
Abstract: By means of single-crystal X-ray diffraction, we give direct crystallographic evidence of a centrosymmetry breaking below TS = 200 K, concomitant with the onset of a commensurate structural modulation in the quadruple perovskite YMn3Mn4O12. This… read more here.

Abstract: The quadruple perovskite oxides RCu3Fe4O12 (R: rare-earth metals) exhibit large latent-heat capacities (25 J g-1 at maximum) with variable transition temperatures between 254 and 368 K, whereas their transition entropies are almost completely retained. This… read more here.

DOI: 10.1103/physrevb.98.104423
Abstract: We report a neutron powder diffraction study of $R$Mn$_7$O$_{12}$ quadruple perovskite manganites with $R$ = La, Ce, Nd, Sm, and Eu. We show that in all measured compounds concomitant magnetic ordering of the $A$ and… read more here.
