Assignee: KEIO UNIVERSITY
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A magnetic memory comprising:
a first ferromagnetic layer;
a non-magnetic layer provided on the first ferromagnetic layer;
a second ferromagnetic layer provided on the non-magnetic layer;
a first conductive layer provided on the second ferromagnetic layer; and
a second conductive layer having carrier mobility or electrical conductivity lower than the carrier mobility or electrical conductivity of the first conductive layer and provided on the first conductive layer, wherein
a spin current is generated by rotation of a velocity field of an electron caused by a change in carrier mobility or electrical conductivity at a boundary between the first conductive layer and the second conductive layer, and
information is stored by controlling a direction of magnetization of the second ferromagnetic layer by using the spin current.
