Studies on the power factor of (Ba,Sr)Co2+xRu4−xO11 compounds 

Pato Doldán, Breogán; Sánchez-Andújar, Manuel; Castro-García, Socorro; Señarís-Rodríguez, M. A. (Elsevier, 2011-02)
[Abstract] We have prepared polycrystalline single-phase ACo2+xRu4−xO11 (A = Sr, Ba; 0 ≤ x ≤ 0.5) using the ceramic method and we have studied their structure, electrical resistivity and Seebeck coefficient, in order to ...

IR characterization of Ln2−xSrxCoO4 (x≥1; Ln=La, Nd) oxides 

Castro-García, Socorro; Sánchez-Andújar, Manuel; Rey Cabezudo, Carlos José; Señarís-Rodríguez, M. A.; Julien, C. (Elsevier, 2001-07)
[Abstract] We have recorded the FTIR spectra of powder samples of Ln2−xSrxCoO4 (Ln=La, Nd) at room temperature. We have identified the infrared active modes (3A2u+4Eu), and analyzed how they change as a function of Ln and ...

Apparent colossal dielectric constants in nanoporous Metal Organic Frameworks 

Sánchez-Andújar, Manuel; Yáñez-Vilar, Susana; Pato-Doldán, Breogán; Gómez-Aguirre, Claudia; Castro-García, Socorro; Señarís-Rodríguez, M. A. (American Chemical Society (ACS), 2012-05-30)
[Abstract] In this work, we show that the hybrid material Co2(1,4-bdc)2(dabco)•[4DMF•1H2O], shows an apparent colossal dielectric constant at room temperature (r5000 at 300 K for =100 Hz). Nevertheless, such response ...
