Abstract
The results of an experimental study of the electrical resistivity of liquid gadolinium at temperatures from 2000 to 4250 K at elevated pressure are presented. Samples of gadolinium (93.0% pure) in the form of plates 80-µm thick were heated by a single current pulse, for a time of about 5–10 µs. Gadolinium plates were placed between two silica-glass plates to preserve the original shape, reduce vaporization, and create some pressure above atmospheric. Electrical resistivity is measured using a high-speed oscilloscope (excluding thermal expansion of gadolinium).
