Abstract Scope |
GMI effect shows the maximum sensitivity at the frequency of 200 MHz [1]. We have studied the effect of the frequency on the sensitivity using a micro coil GMI element. We found interesting results that the coil voltage increases with increase of the frequency up to the frequency of 3GHz. We also found at the frequency of 2GHz the mathematical relationship between the magnetic field and coil voltage shows sine wave function as VVo siniπH/‚QHmj.
We named this new phenomena excited by GHz pulse current as GHz-Spin-Rotation effect[2] and developed on-ASIC type GSR sensor which has the GSR element directly formed on the ASIC. This small size type GSR sensors will be applicable to catheter use.
