Magnetic susceptibility of iron pyrite (FeS 2) between 4.2 and 620 K
Abstract
The magnetic susceptibilities (χ) of several natural single crystals of iron pyrite (FeS 2) 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.
