This paper considers resonant and nonresonant methods for measuring magnetic characteristics of Ni 80 Fe 20 thin films with 1000 Å thickness. The imaginary part of complex magnetic permeability was measured by using resonant and nonresonant measuring cells. The resonant measuring cell included: a micro-strip line, a lumped capacitance, and an amplitude detector. The non-resonant measuring cell included a short-circuited micro-strip line. The studied sample of thin magnetic film is placed under the shortcircuited micro-strip line.The self-resonant frequency of the non-resonant measuring cell is higher than frequency of the ferromagnetic resonance (in field, equal 14 Oersteds). Ferromagnetic resonance method was used to study the change of measuring cell resonant frequency. The angular dependences of resonant frequency were achieved by the change of angle between constant magnetic field and high-frequency field of excitation, the hard axis of magnetization in thin magnetic film. The measurements were carried out using automation units. A numerical comparison of the obtained results showed that the difference between measurements does not exceed 5%.

“…Dispersion of the magnetic anisotropy, magnetization saturation, and other magnetic characteristics reduce the magnetic susceptibility [7,8] and enhance the magnetic noise in a film. It was found that the magnetic noise caused by the spatial dispersion of the magnetic characteristics is the key factor that limits the sensitivity of the magnetic field sensors based on a thin magnetic film [9][10][11]. Usually, during deposition of thin magnetic films an external magnetic field is applied in the film plane.…”
