The polycrystalline indium antimonide Hall probe provides an overall sensitivity of 12500 Volts/ampere-kilo gauss. The device is capable of measuring down to 2 x 10-5 gauss peak in the frequency range dc to 25 c/s. The factors which restrict the lowest limit of magnetic field detection are discussed and methods are suggested to further improve the sensitivity of the device.78 p.Engineering, Electronics and Electrical.Thesis
