发明名称 Patterned MR device with controlled shape anisotropy
摘要 A magnetic sensor with increased sensitivity, lower noise, and improved frequency response is described. The sensor's free layer is ribbon shaped and is closely flanked at each long edge by a ribbon of magnetically soft, high permeability material. This side pattern absorbs external field flux, concentrating it to flow into the sensor's edges to promote larger MR sensor magnetization rotation.
