A method and system for providing and magnetic element is disclosed. In
one aspect, the magnetic element includes at least a pinned layer, a free
layer, and a current confined layer residing between the pinned layer and
the free layer. The pinned layer is ferromagnetic and has a first
magnetization. The current confined layer has at least one channel in an
insulating matrix. The channel(s) are conductive and extend through the
current confined layer. The free layer is ferromagnetic and has a second
magnetization. The pinned layer, the free layer, and the current confined
layer are configured to allow the magnetization of the free layer to be
switched using spin transfer. The magnetic element may also include other
layers, including layers for spin valve(s), spin tunneling junction(s),
dual spin valve(s), dual spin tunneling junction(s), and dual spin
valve/tunnel structure(s).
