    • 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 ...
