Abstract: The paper presents the results of studying the response of $n$- and $p$-type natural pyrite to single electric voltage pulses 50–300 V in amplitude. The sample resistance was found to decrease with increasing voltage amplitude. A dependence of the studied materialsresistances on the pulse polarity was revealed. The data obtained are consistent with the results of previous studies that evidence the presence in natural pyrite of intrinsic field caused by nonuniform impurity distribution in the bulk.

Keywords: pyrite, pulsed electric field, resistivity, nonuniform impurity distribution, diffusion and drift currents.
