Abstract: front page image
(EN)A nano-oscillation element according to one embodiment of the present invention comprises: a first fixed magnetic layer; a second fixed magnetic layer arranged on the first fixed magnetic layer; a free magnetic layer interposed between the first fixed magnetic layer and the second fixed magnetic layer; a first non-magnetic layer interposed between the first fixed magnetic layer and the free magnetic layer; and a second non-magnetic layer interposed between the free magnetic layer and the second fixed magnetic layer. The first fixed magnetic layer has a fixed magnetization direction and is a thin film made of a material to be magnetized in the direction perpendicular to a film surface thereof. The free magnetic layer has a cone state aligned in the direction for maintaining a specific angle with respect to the direction perpendicular to a surface thereof. The second fixed magnetic layer has a fixed magnetization direction and is made of a material to be magnetized in the direction parallel to the film surface thereof.
(FR)La présente invention porte, selon un mode de réalisation, sur un élément de nano-oscillation qui comprend : une première couche magnétique fixe ; une seconde couche magnétique fixe disposée sur la première couche magnétique fixe ; une couche magnétique libre intercalée entre la première couche magnétique fixe et la seconde couche magnétique fixe ; une première couche amagnétique intercalée entre la première couche magnétique fixe et la couche magnétique libre ; et une seconde couche amagnétique intercalée entre la couche magnétique libre et la seconde couche magnétique fixe. La première couche magnétique fixe présente une direction de magnétisation fixe et est un film mince composé d'un matériau à magnétiser dans la direction perpendiculaire à l'une de ses surfaces de film. La couche magnétique libre présente un état de cône aligné dans la direction pour garder un angle spécifique par rapport à la direction perpendiculaire à l'une de ses surfaces. La seconde couche magnétique fixe présente une direction de magnétisation fixe et est composée d'un matériau à magnétiser dans la direction parallèle à l'une de ses surfaces de film.
