Abstract
Methods and apparatus for forming a magnetic tunnel element are provided herein. A method of forming a magnetic tunnel element includes: depositing a magnetic layer atop a cobalt-chromium seed layer; and depositing a tunnel layer atop the magnetic layer to form a magnetic tunnel element, wherein the magnetic tunnel element has a TMR greater than 100. For example, a cobalt/platinum material or one or more layers thereof may be deposited directly atop a cobalt-chromium seed layer to produce improved devices.
