Electrical resistivity of liquid gadolinium $($with carbon content of $29$ at $\%)$ at temperatures of $2000$–$4250$ K

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 $80$-$\mu$m thick were heated by a single current pulse, for a time of about $5$–$10\,\mu$s. 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).
