Abstract

We propose a new method to measure the permeability of striped films. The permeability can be obtained by the change in the input impedance of the film. The sensitivity of these measurements are compared with the figure-eight coil method. The sensitivity of the method is estimated over 100 times greater than a conventional figure-eight coil method. The permeability of striped CoNbZr films (100 μm wide) can be measured accurately using this permeameter.
