摘要：

The temperature dependence of the magnetic susceptibility of FeSi is calculated over a wide temperature range on the basis of spin-fluctuation theory applied to a model of an exchange-enhanced semiconductor. We can reproduce the low-temperature activation-type behaviour of the susceptibility as well as the Curie-Weiss behaviour observed at high temperature. We also give an explanation for the behaviour of the observed wave-vector- and frequency-dependent neutron scattering intensities.
