Claim 17:
18. A spin-orbit torque type magnetization rotational element
comprising:
a spin-orbit torque wiring extending in a first direction;
a first ferromagnetic layer laminated in a second direction intersecting the spin-orbit torque wiring,
a first nonmagnetic metal layer and a second nonmagnetic metal layer which are connected to the spin-orbit torque wiring at positions sandwiching the first ferromagnetic layer in the first direction in a plan view seen in the second direction; and
a second insulating layer surrounding the first ferromagnetic layer,
wherein, in the first direction, a center of gravity of the first ferromagnetic layer is positioned at a position deviating toward either a first nonmagnetic metal layer side or a second nonmagnetic metal layer side from a reference point that is a center between the first nonmagnetic metal layer and the second nonmagnetic metal layer, and
the second insulating layer is any one selected from the group consisting of silicon nitride, aluminum nitride, aluminum oxide, and magnesium oxide.
