摘要

A large body of work has focused on resistivity saturation in systems where scattering is caused by impurities or by thermal effects. Electrical resistivity saturation is here classified as either static, where impurity scattering causes saturation, or dynamic, where changing external parameters such as temperature or pressure cause saturation. Resistivity measurements up to 5GPa show pressure-induced resistivity saturation in Fe17wt%Si by the change in sign from positive to negative of the temperature coefficient of resistivity. The pressure dependence of the Curie temperature is 10.2(8)KGPa(-1). The Debye temperature is calculated from the Bloch-Gruneisen equation and yields a pressure dependence of 40(9)KGPa(-1).
