| Abstract: | According to electromagnetic field perturbation theory and refering to the IEE556 standard measurement system was established for ferromagnetic resonance linewidth. A new wave resonant cavity was designed with the transmission type resonator method, ferromagnetic resonance linewidth can be tested for gyromagnetic materials at frequency of 33GHz, and the test error was analyzed. With the measurement system test problem was solved on ferromagnetic resonance linewidth of the hexagonal ferrites. |
