    • 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 José; 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 [similar] 270 K, associated to a structural phase transition from SG R[3 with combining ...
