Measurement principle

Using DC or AC method to measure the resistivity of the conductor sample and the response of Hall to the magnetic field. The measurement is usually made using a pulse current, that is, a measuring current is applied to the sample while a pulsed magnetic field is generated. This method can not only improve the measurement SNR, but also avoid the temperature change caused by the continuous heating effect of current.
