摘要: A nano-scale linear magnetoresistance sensor is demonstrated using magnetic tunnel junctions with an in-plane magnetized reference layer and a sensing interfacial perpendicular anisotropy. We show that the response depends critically on thickness of since its anisotropy significantly associated thickness. The optimized sensors exhibit large field sensitivity up to 0.02% MR/Oe high range 600 Oe. These findings imply this scheme promising method for developing simple design, sensitivity, low power consumption.
