Una contribución a la preparación, caracterización y estudio de las propiedades de magneto-transporte en perovskitas de cobalto Ln₁-xMxCoO3 (Ln : La, Pr, Nd, Gd; M: Ca, Sr, Ba; 0≤ x ≤ 0.50)

Rey Cabezudo, Carlos José (2017)

[Resumen] Esta Tesis Doctoral se centra en la preparación mediante diversos métodos de "química suave" de óxidos mixtos de cobalto, de fórmula general Lnl -xMxCoO3 (Ln= La, Pr, Nd, Gd; M= Ca, Ba, Sr; 0 < x < 0.50), con ...
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 ...
Peculiarities in the electrical and magnetic properties of cobalt perovskites Ln1−xMxCoO3 (Ln3+: La3+, M2+: Ca2+, Sr2+, Ba2+; Ln3+: Nd3+, M2+: Sr2+)

Señarís-Rodríguez, M. A.; Breijo, M.P.; Castro-García, Socorro; Rey Cabezudo, Carlos José; Sánchez, M.; Sánchez, R.D.; Mira Pérez, Jorge; Fondado Fondado, Alfonso; Rivas Rey, José (Elsevier, 1999-09)

We refer here to the electrical and magnetic properties of the Ln1−xMxCoO3 systems (Ln3+: La3+, M2+: Ca2+, Sr2+, Ba2+; Ln3+: Nd3+, M2+: Sr2+), paying special attention to those ferromagnetic compounds that display M–I ...
