El objetivo del presente trabajo es describir los mecanismos que controlan la coercitividad en composites RE-TM con granos monodominios, en función del tamaño de grano de la fase magnéticamente dura, puntualizar las diferencias respecto al comportamiento de un sistema similar pero de partículas aisladas e identificar el tipo de interacción responsable de las mismas. El composite modelo adoptado para el estudio es policristalino, con tamaño medio de grano en el rango de partículas monodominios y contiene una fase mayoritaria ferromagnética, con anisotropía magnética uniaxial elevada. La distribución de orientaciones de los granos ferromagnéticos en el composite es isotrópica
