| Description: | [EN] Magnetoresistive ceramics, based on half-metallic ferromagnetic oxides have received renewed attention in the last few years because of
their possible applications. Here, we review some recent progress on the development of magnetoresistive ceramic materials such as La2/3Sr1/
3MnO3 and Sr2FeMoO6 ceramic materials. We shall revisit their basic properties, the strategies that have been employed to understand and to
improve their intrinsic properties, pushing the limits of their operation at temperatures well above room-temperature, and the development
of some applications. This effort has required the contribution of a number of actors. Starting from research laboratories, it has progressively
involved industries that nowadays are able to supply high quality raw-materials or to manufacture magnetoresistive components at large
scale. [ES] Las cerámicas magnetorresistivas, basadas en óxidos semi-metálicos ferromagnéticos han recibido una renovada atención en los últimos años debido a sus posibles aplicaciones. Se revisan aquí algunos de los recientes progresos en el desarrollo de materiales cerámicos magnetorresistivos como La2/3Sr1/3MnO3 y Sr2FeMoO6. Se revisitan sus propiedades básicas, las estrategias empleadas para entender y mejorar sus propiedades intrínsecas, llevando sus límites de operación a temperaturas muy por encima de temperatura ambiente, y el desarrollo de algunas aplicaciones. Este esfuerzo ha requerido al contribución de un gran número de actores. Comenzando por laboratorios de investigación, se ha implicado progresivamente a industrias que hoy en día están capacitadas para suministrar materias primas de alta calidad o para fabricar componentes magnetorresistivos a gran escala. This work has been supported in part by the AMORE project of the E.U., and the DIMOS and MAT2002-03431 projects of the MCyT (Spain). We are thankful to E. Jedryka, M. Wojcik, S. Nadolski, for performing the NMR spectra and fruitful discussions. Peer reviewed |
