Current-in-Plane Giant Magnetoresistance Sensor Using a Thin Cu Spacer and Dual Nano-Oxide Layers With a Greater Than 20 Ohms/sq

The magnetoresistance (MR) of the current-in-plane spin-valve, which is currently utilized as the readback sensor in the majority of hard disk drives, has reached a maximum MR of DR/R min. ~20% and DR sheet ~4 Omega/sq. A new sensor film stack will be introduced here that utilizes a trilayer (CoFe\C...
