3 , the output linear resolution of the bridge is about to 0 . 84 % and has a better property in comparison of some typical mr angular sensors . 4 , the output sensitivity of the bridge is about 1 . 0667mv / and better than ferrimag angular sensors 4 ，该自旋阀芯片组成的桥路输出的灵敏度达到了1 . 0667mv ，相对于强磁性薄膜为敏感元件的角度传感器有了很大的提高。
In the last twenty years , extensive studies have been made on the structure , basic magnetic properties , interlayer coupling , interfacial structures and its relative effects in magnetic thin and ultrathin films due to their potential application in magnetic random access memory ( mram ) and ultrahigh - density data storage 随着在磁性随机存储器和超高密度存储技术中应用的不断拓展，近二十年来，磁性薄膜和超薄膜的结构、基本磁性、层间耦合、界面状况及其相关效应一直是人们研究的熟点和难点之一。
