This invention provides a multilayer pinned reference layer for a magnetic
device. In a particular embodiment a magnetic tunnel junction cell is
provided. Each magnetic memory tunnel junction cell provides at least one
ferromagnetic data or sense layer, an intermediate layer in contact with
the data layer, and a multilayer pinned ferromagnetic reference layer.
The multilayer pinned reference layer is in contact with the intermediate
layer, opposite from the data layer. The multilayer pinned reference
layer is characterized by at least one first layer of ferromagnetic
material and at least one second layer of ferromagnetic material in
physical contact with the first layer and magnetically coupled to the
first layer. The first and second layer self seed to provide a
<111> crystal texture used in establishing the pinning magnetic
field of the reference layer.
