Abstract

A method is proposed for a simultaneous measurement of the resistivity and permeability of a film inserted between two coils facing each other, Connecting in series, the total impedance of the coils was measured in two ways, i.e., 1) the current passes through the coils in the same direction, and 2) the current passes through each coil in oppositedirections to each other, The resistivity and permeability of the film were simultaneously obtained from the difference in the impedance for the two cases, It was theoretically found that the optimum frequencyfor high accuracy in the measurement was proportional to the resistivity and inversely proportional to a thickness of a sample film. The results of the simultaneous measurements of the resistivity and permeability of nickel films of a thickness ranging from 0.01-0.08 mm at a frequency range of 1-100 kHz are shown in this paper, The measured valuesof the resistivity and permeability with this;method agreed with the values obtained by conventional methods, i.e., the dc four-probe method for the resistivity measurement and the toroidal coil method for thepermeability measurement.
