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 ... -
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 ...
