摘要: The present invention provides a tunneling magneto-resistive read sensor structure that improves sensitivity and linear density of the structure. includes first second electrodes stack positioned between electrodes. free layers with magnetization orientations are biased relative to each other. A barrier (insulating layer) or non-magnetic metal spacer is layers. sense current passed stack. amount passing through layer changes based upon orientation
