A high frequency carrier-type magnetic field sensor [gaint magnetoimpedance (GMI) sensor] probe with a narrow magnetic strip was fabricated. High frequency field detection was performed by this probe. For specific dc bias fields, high sensitivity could be achieved in a wide range of frequency from 5 kHz to 1 GHz. The sensitivity with a high dc bias field was lower than that with a low dc bias field. The outputs of the GMI probe were proportional to input power which generated the ac magnetic field.
