AI总结:

本文提出OpenFMR,一种基于低成本现成组件和3D打印部件、频率达30 GHz的开源宽带铁磁共振谱仪,并配套软件工具,通过1 nm铁磁薄膜测量验证其性能。

摘要:

我们描述了一种用于科学和教育应用的宽带铁磁共振谱仪,频率范围可达30 GHz。它由现成的低成本组件构建,并利用3D打印部件制作样品架和支撑结构,几乎不需要组装。本文提出并分析了一种接地共面波导(GCPW)的PCB设计。我们还提供了一套软件套件,用于命令行或脚本驱动的数据采集、一个图形用户界面以及一个图形化数据分析程序。通过对厚度为1 nm的铁磁薄膜进行测量,展示了该系统设计的能力。所有设计和脚本均根据GNU GPL v3.0许可证发布。

英文摘要:

We describe a broadband ferromagnetic resonance spectrometer for scientific and educational applications with a frequency range up to 30 GHz. It is built with low-cost components available off-the-shelf and utilizes 3D printed parts for sample holders and support structures, and requires little assembly. A PCB design for the grounded coplanar waveguide (GCPW) is presented and analysed. We further include a software suite for command-line or script driven data acqusition, a graphical user interface, and a graphical data analysis program. The capabilities of the system design are demonstrated with measurements on ferromagnetic thin films with a thickness of 1 nm. All designs and scripts are published under the GNU GPL v3.0 license.
