We propose a new method to measure the permeability of striped films. The p
ermeability can be obtained by the change in the input impedance of the fil
m. The sensitivity of these measurements are compared with the figure-eight
coil method. The sensitivity of the method is estimated over 100 times gre
ater than a conventional figure-eight coil method. The permeability of stri
ped CoNbZr films (100 mum wide) can be measured accurately using this perme
ameter.
