Abstract

In this paper, the synthesis, resistivity measurement, and X-ray diffraction of the Fe-Sb system are reported. The method of synthesis of the Fe-Sb system, which instigates the formation of the FeSb2 and FeSb phases between Fe grains at the interface, was found to cause a decrease in resistivity. The sample produced an anomalous result for resistivity behavior at room temperature, where a time-dependent change in the electrical resistivity was observed. This change can be expressed by the exponential function of time.
