Title:
MAGNETIC ARRAY, CONTROL METHOD FOR MAGNETIC ARRAY, AND OPERATION PROGRAM FOR MAGNETIC ARRAY
Document Type and Number:
WIPO Patent Application WO/2023/170816
Kind Code:
A1
Abstract:
This magnetic array comprises: a plurality of magnetoresistance effect elements; and a pulse application device that applies a pulse to at least one of the plurality of magnetoresistance effect elements. Each of the plurality of magnetoresistance effect elements comprises: a domain wall movement layer; a ferromagnetic layer; and a non-magnetic layer interposed between the domain wall movement layer and the ferromagnetic layer. The pulse application device outputs a first pulse and a second pulse at different times. The voltages of the first pulse and the second pulse are both voltages by which it is possible to attain a current density greater than or equal to the critical current density required to move the domain wall of the domain wall movement layer. The second pulse is greater in voltage or pulse length than the first pulse. The pulse application device outputs the second pulse every set number of times that the first pulse is outputted or at a set probability.
