Magnetoelectric behavior in the complex CaMn7O12 perovskite
[Abstract] We report a magnetoelectric effect in the double perovskite CaMn7O12, that shows a complex magnetic behavior below 90 K with two magnetic phases coexisting (one ferrimagnetic and the other modulated). A second ...
Charge ordering and dielectric properties in the near half-doped Pr0.79Na0.21MnO3 perovskite
[Abstract] The Pr0.79Na0.21MnO3 perovskite has been prepared in polycrystalline form by a ceramic method. We have carried out its structural characterization by synchrotron X-ray powder diffraction (SXRPD) at room temperature ...
A simple solvothermal synthesis of MFe2O4 (M=Mn, Co and Ni) nanoparticles
[Abstract] Nanoparticles of MFe2O4 (M=Mn, Co and Ni), with diameters ranging from 5 to 10 nm, have been obtained through a solvothermal method. In this synthesis, an alcohol (benzyl alcohol or hexanol) is used as both a ...
Near room temperature dielectric transition in the perovskite formate framework [(CH3)2NH2][Mg(HCOO)3]
(The Royal Society of Chemistry, 2012-05)
[Abstract] We report that the hybrid organic–inorganic compound [(CH3)2NH2][Mg(HCOO)3] shows a marked dielectric transition around Tt [similar] 270 K, associated to a structural phase transition from SG R[3 with combining ...
