Abstract
Integrated circuits and methods of producing the same are provided. In an exemplary embodiment, a method of producing an integrated circuit includes forming a fixed layer that includes a magnetic material overlying a substrate. A non-magnetic first tunnel barrier layer is formed overlying the fixed layer. A total free layer is formed overlying the first tunnel barrier layer, where the total free layer includes a first spacer layer between first and second free layers. The first free layer includes one or more of cobalt, iron, and boron. The first spacer layer is non-magnetic and includes a first spacer layer boron sink material that has a boride formation enthalpy lower than the boride formation enthalpy of cobalt.
