求助摘要翻译（巨磁电阻）
|
|||
| 本文简要介绍了磁电阻效应的分类、发展历程及其应用，重点介绍了巨磁电阻效应，包括多层磁阻薄膜、自旋阀、颗粒膜、自旋隧道磁电阻、“非连续”多层膜等。实验以Cu 作为非磁层，采用直流磁控溅射技术在Si基片上制备了Cu/ Ni0.36 Fe0.64磁性多层薄膜样品，总厚度为300纳米，调制周期为20纳米，其中Cu和Ni0.36Fe0.64膜各15层，每周期中Cu膜厚为15.4纳米，Ni0.36Fe0.64膜厚为4.6纳米。将制备的薄膜样品分为两组，一组在400℃下真空退火30min，另一组作为对照。实验结果表明：退火后样品的薄膜电阻率显著减小，是未退火样品薄膜电阻率的3.17分之一；而退火后磁电阻值则明显增加，是未退火时的1.74倍；XRD结构分析显示，退火后薄膜样品的峰值强度大于未退火样品的强度，说明样品结晶度增强。 |

This paper gives a brief introduction for the classification, development and application of magnetoresistance effect and focuses on giant magnetoresistance effect, including multilayer magnetic resistance film, spin valve, membrana granulosa, spin tunnel magneto-resistor, discrete multilayer film and so on.In the experiment we used Cu as non-magnetosphere and prepared Cu/ Ni0.36 Fe0.64 magnetic multilayer film samples with a total thickness of 300nm and a modulation period of 20nm on the Si substrate by DC magnetron sputtering. There are 15 layers of Cu film and Ni0.36Fe0.64 film respectively and the thickness of Cu film is 15.4nm per period while Ni0.36Fe0.64 film is 4.6nm. Divided the prepared samples into two groups, one was annealing 30min in vacuum at 400℃ and the other was a comparison. The experimental results indicated that the film resistivity of the sample annealed was reduced significantly and only one 3.17 of the unannealed. However, the value of magnetoresistance increased apparently after annealing and was 1.74 times the unannealed sample. XRD structural analysis shows that peak intensity of the annealed sample is greater than that of the unannealed one which demonstrated an increase of crystallinity. 3.17分之一可能不对，楼主自己再修改下 |
