Ferromagnetic resonance is a powerful method for the study of all classes magnetic materials. The experimental technique has been used many decades and based on excitation spin system via microwave (or rf) field. While earlier methods were use spectrometer, more recent developments have seen widespread vector network analyzer (VNA), which provides versatile measurement at almost comparable sens...

Nanocrystalline Co40Fe40B20 films, with film thickness tf = 100 nm, were deposited on glass substrates by the magnetron sputtering method at room temperature. During the film deposition period, a dc magnetic field, h = 40 Oe, was applied to introduce an easy axis for each film sample: one with h||L and the other with h||w, where L and w are the length and width of the film. Ferromagnetic resona...
