NEW COMPLEX PERMEABILITY MEASUREMENT DEVICE FOR THIN MAGNETIC-FILMS

Previously, we have proposed a strategic dual image (SDI) method to ob tain the finite element solution of open boundary magnetic field probl ems. Also, we have derived a complex permeability from a Chua-type mag netization model. Combination of this complex permeability with the SD I method is now applied to exploit a new high frequency characteristic measurement device for thin magnetic films. Numerical simulation sugg ests that our new measurement method yields far superior results compa red with those of the conventional one.
