Abstract
LA INVENCION SE REFIERE A CERAMICAS MAGNETICAS Y SU APLICACION COMO REFRIGERANTES MAGNETICOS, QUE CORRESPONDEN A LA FORMULA GENERAL ABO3 EN LA QUE A ES UN ION METALICO (LA3 +, CA2 +, BA2 + O SR2 +) Y B ES UN CATION MAGNETICO TAL COMO FE, CO O MN, PUDIENDO SER TANTO A COMO B - UNA COMBINACION DE DIFERENTES CATIONES Y TAMBIEN DICHOS CATIONES PARE DEN ENTRAR EN CONCENTRACIONES DIFERENTES PERO SIEMPRE MANTENIENDO LA NEUTRALIDAD DE CARGA ELECTRICA. ASIMISMO, DADA UNA DETERMINADA FORMULA UNIDAD, ES POSIBLE VARIAR LA ESTEQUIOMETRIA DEL OXIDO CORRESPONDIENTE SIN MAS QUE MODIFICAR EL CONTENIDO DE OXIGENO DE LA ATMOSFERA OXIDANTE DURANTE LA PREPARACION QUIMICA DEL MISMO. COMO RESULTADO DE TODO ESTE PROCESO DE CAMBIO DE LA COMPOSICION Y DE LA ESTEQUIOMETRIA, LA TEMPERATURA DE CURIE DE LOS DIFERENTES COMPUESTOS QUE SE OBTIENEN ESTA COMPRENDIDA ENTRE LOS 80K Y 673K.
