Abstract
A magnetic device includes a stacked body including a first ferromagnetic layer, a second ferromagnetic layer, and a non-magnetic layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer; a first insulating layer which covers side surfaces of the stacked body; and a radiator located outside the first insulating layer with respect to the stacked body, in which a distance between the stacked body and the radiator differs depending on a position of the stacked body in a stacking direction.
Claims16
A magnetic device comprising:
- a stacked body including a first ferromagnetic layer, a second ferromagnetic layer, and a non-magnetic layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer;
- a first insulating layer which covers a side surface of the stacked body;
- a first radiator located outside the first insulating layer with respect to the stacked body;
- a second radiator located outside the first insulating layer with respect to the stacked body;
- and
- a wiring connected to the stacked body,
- wherein a distance between the side surface of the stacked body and the first radiator differs depending on a position of the stacked body in a stacking direction, and a magnetization of the first ferromagnetic layer is reversed by flowing a current along the wiring,
- the wiring, the first radiator and the second radiator extend along a first direction respectively, and
- the wiring is sandwiched between the first radiator and the second radiator at a same height position as the wiring in a direction that intersects the first direction.
