Abstract

Procedimiento para aumentar la temperatura de Curie en óxidos magnetoresistivos con estructura de doble perovskita. Esta invención se refiere a un procedimiento para aumentar la temperatura de orden ferromagnético (temperatura de Curie, T{sub,C} en óxidos ferromagnéticos tipo doble perovskita A{sub,2}BB''O{sub,6} donde B y B'' son iones metálicos (B=Cr,Fe,Co,... y B''=Mo, Re, W,...). Algunos de estos óxidos son metálicos y ferromagnéticos y presentan una magnetoresistencia (cambio de su resistencia eléctrica al ser sometidos a un campo magnético) importante, por lo que pueden ser usados en dispositivos y sensores magnetoresistivos. La presente invención incluye los materiales tipo A{sub,2}BB''O{sub,6} preparados con la composición y procedimiento que se describirán así como los dispositivos magnetoresistivos (por ejemplo, sensores magnéticos, memorias magnéticas, cabezales de lectura magnéticos, etc.) que en base a ellos se pudieran fabricar.
