Negative resistance element using magnetoresistance effect

摘要

Negativity comprising a magnetoresistive element having a magnetization free layer (33), a magnetization fixed layer (31) having a magnetic moment greater than the magnetic moment of the magnetization free layer, and an intermediate layer (32) disposed between the magnetization free layer and the magnetization fixed layer Resistance element. It is characterized in that a change in the magnetization direction of the magnetization free layer is continuously caused as the voltage applied to the magnetoresistive element is increased so that electrons flow from the magnetization free layer side, thereby showing a negative resistance.
