| 摘 要： | 用射频溅射的方法制备得的钆钴膜具有垂直于膜面的单轴各向异性。电子衍射结果表明薄膜是非晶态的。电子探针分析证明钆和钴的“混合”是均匀的。用极向克尔效应观察了样品的磁畴,并测量了相应的磁滞迴线;发现在一定的工艺条件下,制备得的样品,在退磁状态呈现条状畴,并在一合适的外磁场作用下能转变为磁泡。

| Abstract: | The Gd-Co films reported here were prepared by radio frequency sputtering and have been proved to have uniaxial anisotropy perpendicular to the film plane. Electron diffraction results show that these films are amorphous. Also, electron probe analyses show that these films are of uniform composition. Magnetic domains have been observed and hysteresis loops measured, using Kerr's apparatus. It was found that with suitable sputtering conditions, at remanence such films exhibit stripe domains, which, when acted on by a suitable external field perpendicular to the film plane, can transform into bubble domains. |
