“…Fig. 4 showed the frequency dispersion of complex permeabilities l r 0 and l r 00 of fabricated Ni-Zn-Cu ferrite film at 1200 1C where l r 0 and l r 00 were corrected after the absolute value correction method [5]. In the figure, simultaneously the frequency dispersion of the sintered sample using the same powder as that of fabricated film was inserted in order to compare with the ADM sample.…”

“…From the viewpoint of film thickness, ADM has higher speed deposition rate of film with much larger thickness, compared with sputtering or ferrite plating method [3]. Till date there are samples of PZT [4] and Al 2 O 3 [5]. But the application of ADM to the fabrication of soft magnetic material film has not been reported in the literature.…”

A highly sensitive probe to measure thin film permeability was developed based on the skin effect. A microstrip-line-type probe on a flexible polyimide substrate was fabricated and placed in contact with a magnetic thin film. The permeability was optimized by the Newton-Raphson method. The permeability of amorphous Co85Nb12Zr3 film (25 mm x 25 mm and 5 nm in thickness) was evaluated using a permeameter. The measured values were in rough agreement with theoretical values based on the Landau-Lifshitz-Gilbert equation and eddy current generation up to 7 GHz. The proposed method shows promise for the measurement of very thin film (less than 10 nm in thickness) because the contact surface between the flexible probe and thin film fits very well, resulting in improvement of the signal-to-noise ratio.
