【Abstract】 In the present paper,a new method for determining the complex permeability of thin magnetic films is adopted.The measurement technique was carried out by a one-port permeameter,which is based on a short-circuited microstrip and frequency sweep.After introducing the measurement process,we chiefly show that the frequency-dependent permeability is affected by the electrical resistivity of the ferromagnetic layer,correct factor K as well as system calibration procedure and so on,and present the methods of reducing errors that have resulted from these factors,to help to improve the precision of the measurement.更多还原
