High metallic resistivities and resistivity saturation : High-pressure and thermal expansion effects

• Some recent developments in the field of resistivity saturation in metallic materials are discussed, concentrating on effects of thermal expansion and high pressures. It is shown that thermal expansion effects can significantly modify the measured temperature dependence of the resistivity, and that high pressure studies are an important, but little used, source of information. Examples are shown for transition metals and alloys, high transition temperature superconductors, and graphite intercalation compounds.
