MAGNETIC ARRAY, CONTROL METHOD FOR MAGNETIC ARRAY, AND OPERATION PROGRAM FOR MAGNETIC ARRAY

Abstract: a magnetic array includes a plurality of magnetoresistance effect elements and a pulse application device configured to apply a pulse to at least one of the plurality of magnetoresistance effect elements. each of the plurality of magnetoresistance effect elements includes a magnetic domain wall movement layer, a ferromagnetic layer, and a nonmagnetic layer interposed between the magnetic domain wall movement layer and the ferromagnetic layer. the pulse application device outputs a first pulse and a second pulse at different times. voltages of both the first pulse and the second pulse are voltages at which a current density equal to or higher than a threshold current density required for moving a magnetic domain wall of the magnetic domain wall movement layer is acquired. the second pulse has a higher voltage than the first pulse or a longer pulse length than the first pulse. the pulse application device outputs the second pulse whenever the first pulse is output at a prescribed frequency or with a prescribed probability.
