PROBLEM TO BE SOLVED: To realize a magnetoresistance element capable of high-speed magnetization reversal and having low critical current density, and provide a solid memory.;SOLUTION: A magnetoresistance effect element comprises a first magnetization fixed layer, a magnetization free layer, and a second magnetization fixed layer. The first magnetization fixed layer is roughly anti-parallel to the second magnetization fixed layer. Both of transition regions between the first magnetization fixed layer and the magnetization free layer and between the second magnetization fixed layer and the magnetization free layer can trap magnetic domain walls, and there is provided a structure in which the magnetic domain wall exists in either one of them. Between the first and second magnetization fixed layers, pulse current having the DC current density with a pulse width of 1 ns that is a value not exceeding 106 A/cm2 is supplied.;COPYRIGHT: (C)2007,JPO&INPIT
