Abstract: | The magnetic susceptibilities (χ) of several natural single crystals of iron pyrite (FeS2) have been measured between 4.2 and 620 K with a force magnetometer. The measured susceptibilities are shown to related to the magnetic impurities present in the samples. For a pure sample, χ = 1.7 × 10?7 emu/g at room temperature, with a small monotonic increase of χ with temperature. The results for a pure sample are interpreted in terms of contributions from diamagnetism and Van Vleck paramagnetism. |
