美国艺术与设计论文代写-实验分析

本文主要讲实验分析,采用四种实验装置分析了薄膜磁化表面的极化效应。第一种是纵向克尔磁强计,第二种是微聚焦克尔显微镜、极坐标显微镜和二次效应显微镜。纵向克尔磁强计或简单的纵向MOKE是一种探测磁性薄膜准静态特性的仪器。它支持一个光学分辨率近似量∼100μm,磁场0.2 t,也可以构建一个自动化样品定位旋转。克尔显微镜也可以用旋转装置来制作。本篇美国艺术与设计论文代写文章由美国论文通AssignmentPass辅导网整理,供大家参考阅读。

Four experimental setups are used in the analysis of the polarization effects on the thin film magnetized surfaces. The first of them is the Longitudinal Kerr magnetometer and the second is the micro focused Kerr microscope, polar and the quadratic effects MOKE. The Longitudinal Kerr magnetometer or simply the Longitudinal MOKE is one that probes for quasi-static properties with respect to magnetic thin films. It supports an optical resolution to the amount approximating to ∼ 100 μm, a magnetic field up to a 0.2T and also can be built as an automated sample positioning one with rotation. The Kerr microscope could be built with a rotation unit as well.
The rotation unit applied here ensures that the microstructure magnetic materials are studied as well. Here it is identified that the optical resolution is well under a micro m. On a similar note, it is identified that the field settings might reflect 60 m T. The dual MOKE on the other hand is seen to combine two or more of the MOKE magnetometers and this works in parallel. One would work in the longitudinal context and the other in the polar and this supports an optical resolution of around approximately 100 μm. One of the commonly used classification schema for the magneto-optical Kerr effect (MOKE), needs to be defined using a dual definition. These need to be based simultaneously on Cartesian coordinate components that are a part of the magnetization vector.
These need to be defined with respect to plane of incidence reference frame and alongside the specific elements of reflection matrix. This is found to describe light reflection that are formulated from the ferromagnetic surface. There is an unambiguous correspondence that is found between reflection matrix elements and the magnetization components. These are found to be only in specific cases. In the cases of general attitudes these are found to leads towards the inconsistencies that are found to arise due to intermixing of assumed separate effects the longitudinal and polar MOKE. To understand the nuances of the process there must be investigation of the work that are both theoretical and experimental.
