摘要随着电子信息产业的快速发展，为了提高数据的传输速率和节省空间，一个显著的趋势是电子元器件的工作频率和集成度不断的在提高。作为电子元器件关组成部分之一的磁性元器件必然要适应这种趋势而向高频化、小型化方向发展。工作在1GHz以上的高磁导率磁性材料是发展磁性电子器件，进而实现电子系统大集成的瓶颈。67160
想要获得高磁导率磁性薄膜，就要提高面内各向异性，然而一般的薄膜不会自发产生面内各向异性，需要采用各种辅助诱导手段，倾斜溅射就是一种诱导手段。倾斜溅射不同于一般的垂直磁控溅射，它是使得样品偏离正靶位而发生的磁控溅射现象。本实验通过改变样品的倾斜角来实现倾斜溅射，倾斜溅射可以提高薄膜的各向异性。本文研究的对象是CoZr薄膜。CoZr薄膜属于过渡族金属-金属型（TM-M型）非晶态合金薄膜。这种薄膜具有较高的饱和磁化强度和较高的晶化温度及Curie温度，与此同时具有优良的软磁特性。本次毕业设计的主要目的是首先了解磁控溅射的原理，以及何为倾斜溅射，然后通过测量在不同角度样品台上的样品的磁滞回线，比较各向异性场等磁性参数随倾斜角度的变化。

Title The tuning of anisotropy and microwave characteristics of soft magnetic film by oblique sputtering
Abstract
With the rapid development of electronic information industry, in order to improve the data transfer rate and save space, a significant trend is that the electronic components operating frequency and integration are constantly increasing. As part of one of the electronic components, the magnetic component is bound to adapt to this trend and towards high frequencies, miniaturization direction .Work in more than 1 GHz high permeability magnetic material is the bottleneck that the development of magnetic electronic components, thus achieving a large integrated electronic system.
To get a high permeability magnetic film, it is necessary to improve the in-plane anisotropy, however, the film does not spontaneously general plane anisotropy, and it requires the use of various auxiliary induction means, such as inclined sputtering. Unlike the vertical magnetron sputtering, inclined sputtering is a phenomenon that makes the sample deviate from target then occurred magnetron sputtering. The experiment by changing the sample tilt angle to achieve the Inclined sputtering, and Inclined sputtering can improve the film anisotropy. This study focused on CoZr film. CoZr film belongs to the transition metal - metal type (TM-M-type) amorphous alloy films. This film has a high saturation magnetization and higher crystallization temperature and the Curie temperature, at the same time it has excellent soft magnetic properties. The main purpose of graduation project is to understand the principle of magnetron sputtering and sputtering what is Inclined, and then by measuring hysteresis loop of the samples at different angles of sample stage, and then compared magnetic anisotropy field changes with the Inclined angle.
