摘要： A magnetic element comprises a granular magnetic film which has ferromagnetic fine particles dispersed in a dielectric matrix and does not display superparamagnetism and further possesses a finite coercive force, and a ferromagnetic film. A granular magnetic film and a ferromagnetic film are stacked or arrayed along one surface of a substrate and constitutes a ferromagnetic tunnel junction film. In the ferromagnetic tunnel junction film, the granular magnetic film functions as a barrier. Of the granular magnetic film and the ferromagnetic film, by varying spin direction of one ferromagnetic film through an external magnetic field, a giant magnetoresistance effect is manifested. Such a magnetic element is characterized in that magnetoresistance change rate is large, saturation magnetic field is small, resistance of the element can be controlled to an appropriate value, performance is small in its variation and stable.

摘要： A discrete energy levels are introduced in a ferromagnetic layer of a magnetic device, and tunnel current flows through a plurality of tunnel junctions. The tunnel junctions are disposed between first and second electrodes and the first ferromagnetic layer is interposed between the two tunnel junctions. Variations of the tunnel current depend on the relationship between magnetization directions of the ferromagnetic layer and another ferromagnetic layer. Tunnel current varies between parallel relation and anti-parallel relation.
