ABSTRACT:
Fe rich CoFe can be used in AP1 to enhance CPP GMR. However, this is found to degrade the electro-migration performance of the device. This problem has been solved by using an AP1 that is a laminate of several CoFe(25%) layers, separated from one another by copper layers. Ultra-thin layers of iron-rich CoFe are then inserted at all the copper-CoFe interfaces.
