We designed high-frequency-carrier type thin film sensors to obtain high impedance change. We considered the relationships between carrier current density and noise level, carrier current density and sideband level, and optimum impedance of sensor element. The meander type sensor element fabricated had an impedance change of 30 Ω/Oe at 500 MHz. Sensitivity of 4.5×10-8 Oe was demonstrated at 501 kHz using a carrier-suppression technique.
