Abstract
We examined a laminated high-frequency carrier-type thin-film magnetic fiel d sensor that consists of CoNbZr soft magnetic films with Nh nonmagnetic co nductive interlayer. The lamination can change domain structure of the sens or and obtain high sensitivity. An impedance change of 6 Omega and a gain o f 43 k Omega /T was achieved when the length of the laminated sensor was 1 mm. The gain is four times larger than that of a monolayer sensor.
