Abstract
This study reports the performance of a high-frequency carrier-type thin-film magnetic field sensor that uses impedance change at high frquencies. To obtain high resolution, we reduced environmental electromagnetic noise and used high resolution instruments. A voltage change ratio (similar to the MR ratio) of 26.7% was achieved when ac carrier frequency was 400MHz. The resolution of the sensor was dc 2×10^<-4>Oe and ac 8×10^<-5>Oe, respectively.
