| 摘 要： | 利用反应溅射的方法制备了ＮｉＯ薄膜，并研究了ＮｉＯ对ＮｉＦｅ薄膜的钉扎作用结果表明钉扎场与反应溅射的Ａｒ／Ｏ２比例，总的溅射气压、基底的粗糙度等有很大关系，利用光电子能谱（ＸＰＳ）分析了ＮｉＯ２中的Ｎｉ２Ｏ离子的价态，并制备了ＮｉＯ钉扎的自旋阀Ｔａ／ＮｉＯ／ＮｉＦｅ／Ｃｕ／ＮｉＦｅ／Ｔａ，其磁电阻（ＭＲ）可达到２．２％，忆场为１０．４８ｋＡ／ｍ。 |

| Abstract: | The exchange fields of NiO/NiFe bilayer have been investigated, and the NiO film is deposited by dc magnetron reactive sputtering .It has been shown that exchange field is relation to the ratio of Ar/ O_2 (Volume ration), total sputtering pressure and the roughness of substrate.The Ni and O ion in NiOx is analyzed by means of XPS.The spin-vavie Ta/NiO/NiFe/Cu/NiFe/Ta pinned by NiO is deposited, and its magne- toresistance reaches 2.2 % and pinning field is 10.48 KA/m. |
