宽带铁磁共振（bbFMR）光谱是一个既定的实验工具，以量化磁性能。由于微波装置的频率依赖性传输，频域中的bbFMR测量需要合适的背景去除方法。在这里，我们提出了一个测量和数据分析协议，使我们能够执行定量的频率扫描bbFMR测量，而无需校准的微波设置。此外，我们比较了建议的频率空间分析和传统的分析从坡莫合金薄膜获得的bbFMR数据的场空间的结果。用这两种方法提取的参数非常好的协议表明我们的方法的可靠性。
Broadband ferromagnetic resonance (bbFMR) spectroscopy is an established experimental tool to quantify magnetic properties. Due to frequency-dependent transmission of the microwave setup, bbFMR measurements in the frequency domain require a suitable background removal method. Here, we present a measurement and data analysis protocol that allows us to perform quantitative frequency-swept bbFMR measurements without the need for a calibration of the microwave setup. We furthermore compare the results of the proposed frequency space analysis and a conventional analysis in field-space of bbFMR data obtained from a permalloy thin film. The very good agreement of the extracted parameters using the two methods shows the reliability of our method.
