FeMn : AntiFerro
CoFe : Ferro (pinned)
Cu : Spacer
CoFe : Ferro (free) The above figure is the standard profile picture of a GMR spin-valve, normally used as the read-head of
hard drive. The top antiferromagnetic plays a role in pinning the first ferromagnetic without the
influence of external magnetic field. Therefore, the spin of top ferromagnetic is determined by the
