A simple solvothermal synthesis of MFe2O4 (M=Mn, Co and Ni) nanoparticles
Yáñez Vilar, Susana; Sánchez-Andújar, Manuel; Gómez Aguirre, Lilián Claudia; Mira Pérez, Jorge; Señarís-Rodríguez, M. A.; Castro-García, Socorro (Elsevier, 2009-10)[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 ... -
Charge ordering and dielectric properties in the near half-doped Pr0.79Na0.21MnO3 perovskite
Sánchez-Andújar, Manuel; Yáñez Vilar, Susana; Castro-García, Socorro; Señarís-Rodríguez, M. A. (Elsevier, 2008-06)[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 ... -
Magnetoelectric behavior in the complex CaMn7O12 perovskite
Sánchez-Andújar, Manuel; Yáñez Vilar, Susana; Biskup, Nevenko; Castro-García, Socorro; Mira Pérez, Jorge; Rivas Rey, José; Señarís-Rodríguez, M. A. (Elsevier, 2009)[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 ... -
Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃]
Pato Doldán, Breogán; Sánchez-Andújar, Manuel; Gómez Aguirre, Lilián Claudia; Yáñez Vilar, Susana; López-Beceiro, Jorge; Gracia Fernández, Carlos; Haghighirad, A. A.; Ritter, F.; Castro-García, Socorro; Señarís-Rodríguez, M. A. (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 ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c ...
