Abstract:
A ferromagnetic tunnel magnetoresistive element, comprising: a first half-metallic ferromagnetic layer; a first insulating barrier layer formed on the first half-metallic ferromagnetic layer; a ferromagnetic metal layer formed on the first insulating barrier layer; a second insulating barrier layer formed on the ferromagnetic metal layer; and a second half-metallic ferromagnetic layer formed on the second insulating barrier layer,wherein the element further comprises a terminal for applying a first bias voltage between the first half-metallic ferromagnetic layer and the second half-metallic ferromagnetic layer, and a terminal for applying a second bias voltage between the ferromagnetic metal layer and the first or second half-metallic ferromagnetic layer.
