Abstract:
A magnetic element, comprising:ferromagnetic-dielectric mixed layer having ferromagnetic material and dielectric material; the ferromagnetic material in the ferromagnetic-dielectric mixed layer having volume not smaller than that of the dielectric material in the ferromagnetic-dielectric mixed layer, first and second tunnel dielectric barriers respectively formed on the ferromagnetic-dielectric mixed layer, first layer of ferromagnetic material formed so that the first dielectric barrier is interposed between the ferromagnetic-dielectric mixed layer and the first layer of ferromagnetic material; and second layer of ferromagnetic material formed on the second dielectric barrier so that electric current flowing between the first and second layers of ferromagnetic material flows through each of the first and second dielectric tunnel barriers and the ferromagnetic-dielectric mixed layer.
