Abstract
The present invention provides a magnetoresistive effect element which performs writing by a novel method. In a state in which a current does not flow in a magnetization free layer MFR, the magnetization free layer MFR has a magnetic wall MWon the side of a magnetization fixed layer MFX. A magnetic wall MWis moved to the magnetic wall MWside by causing current to flow from the formed side of the magnetic wall MW. Thus, an electrical resistance Rbetween a reference layer REF and the magnetization free layer MFR changes from a low state to a high state.
