CPP spin valve head with bias point control |
摘要 |
High sensitivity in a CPP spin valve has been achieved by providing an extended free layer while maintaining good bias point control and edge domain control through use of exchange coupling with the whole free layer. In a second embodiment of the invention, a second spin valve is added so that the free layer receives filtered electrons from two directions. Processes to manufacture both embodiments are also described.
