Abstract
A magneto-resistive device has a magnetic free layer (), a magnetic pinned layer () having a magnetic moment larger than that of the magnetic free layer, and an intermediate layer () provided between the magnetic free layer and the magnetic pinned layer. The negative-resistance device is characterized in that the negative-resistance device shows negative resistance by making the magnetic free layer continually change the magnetization direction along with the increase of the voltage which is applied to a magneto-resistive device so that electrons flow into the negative-resistance device from a magnetic free layer side.
