Abstract
A magnetic device (40) having multi-layer (41-45) with insulating layer (45) and conductive layer (42). The conductive layer (42) is positioned between a first magnetic layer (41) and a third magnetic layer (44). The insulating layer (45) is positioned between a second magnetic layer (43) and the third magnetic layer (44), and which forms a tunnel junction between the second and third layers. Magnetic vectors in the first magnetic layer (41) magnetically couple with ones in the second magnetic layer (43) so that the magnetic coupling loop formed around the third magnetic layer (44) allows magnetic vectors in the third magnetic layer (44) to be switchable in a low magnetic field. Consequently, total power consumption of the magnetic device (60) decreases.
