| Outline of Final Research Achievements |
We investigated magnetic field detection properties of small fields, offset fluctuations of the output voltage, and power spectrum of noise. On the sensitivity, it was found that the InSb Hall element can detect the magnetic field of 1 uT precisely, and the maximum fluctuations and the standard deviation are about ±250 nT and 130 nT, respectively. In the noise spectrum, 1/f noise was observed in wide range of frequency and its power density is proportional to the input current.
