Abstract
An improved and novel fabrication method for a magnetic element, and more particularly a magnetic element ( ) including a first electrode ( ) , a second electrode ( ) and a spacer layer ( ). The first electrode ( ) includes a fixed ferromagnetic layer ( ) having a thickness t . A second electrode ( ) is included and comprises a free ferromagnetic layer ( ) having a thickness t . A spacer layer ( ) is located between the fixed ferromagnetic layer ( ) and the free ferromagnetic ( ) layer, the spacer layer ( ) having a thickness t , where 0.25t <t <2t , thereby producing near zero magnetic field at the free ferromagnetic layer ( ).
