A method for determination of imaginary part of the complex magnetic permeability in thin magnetic films (TMF) is presented. The  measurement of TMF samples by FMR was provided out using the resonant and non-resonant measuring systems. In the resonance  method TMF sample was placed near the segment of microstrip line (MPL). MPL is the inductive part of the resonance measuring cell.  The resonance measuring cell includes: MPL, concentrated capacitance and amplitude detector. The measurements were done with a  sweep of a constant magnetic field and a fixed excitation frequency of the resonant cell. The non-resonant measurements were con

ducted using a vector network analyzer. Frequency sweep of the microwave field changes from 50 to 2000 MHz. The angle between  the constant magnetic field and high-frequency is from 0° to 90°.

The resonance method results in high sensitivity; it does not need any calibration and coordination of measuring cell. The disadvan tage is the narrowband of the measurements and complex automation process because of the continuous resonant frequency meas uring system tuning. The advantage of the non-resonant method is the simplicity of measuring system design and ability to atomize  the measurement process. The disadvantage is the low sensitivity.
