Unformatted text preview: e. If the FeMn (Antiferro) layer is missing, both ferromagnetic layers will always spin in the same direction. And, there will be no high or low resistance states. Reference : http://www.research.ibm.com/research/demos/gmr/index.html (check the flash for how GMR read-head working) 2.b GMR : Major differences are : Two ferromagnetic and spacer are all conductive materials. Current flows parallel to layers. The spin orientation (either antiparallel or parallel) determines the scattering effects of current....
