Abstract Scope |
Through applying GHz pulse current on the amorphous micro wire, we observed an increase in the coil voltage around the wire, and a sine function relationship between the coil voltage and the surrounding magnetic field as V=Vo sin(πH/2Hm)with almost no hysteresis. We assumed that the new performance must be caused by the rotation of electron spins and proposed to name it as GSR (GHz Spin Rotation) effect [1].
We developed the production technology to produce micro coils directly formed on the ASIC surface which make small size GSR sensor possible.
We produced two types of on-chip-coil type GSR sensor which have a length of 0.12mm and 0.45mm and the coil turns of 14 and 66. These two types have larger sensitivity compared to that of the wire bonding type GSR sensor.
