Abstract

See full text

A spin tunneling element includes a pinned layer, a barrier layer, and a free layer. The free layer includes a ferromagnetic layer including a ferromagnetic material that adjoins the barrier layer at a first interface. The free layer also includes a layer of amorphous material that adjoins the ferromagnetic layer at a second interface opposite the first interface. A first crystallization temperature of the ferromagnetic material at the first interface is lower than a second crystallization temperature at the second interface.
