Heat capacity printed: heat capacity	41 J K - ~ per mole of atoms	975		experimental	[1] Liu 1995 cites Baricco 1987 doi	p. 8 report	In the Co-Gd system, the T In(T) term is introduced to fit the heat capacity of the liquid measured by Baricco et al. [ 19], which is about 41 J K - ~ per mole of atoms at about 975 K.

Version 1, machine-extracted: values were read by language-model readers constrained to quote their source and checked automatically, and the release was then audited on the printed pages by adversarial audits, an independent second review of fit-facing records and a preliminary human review of a frozen sample. Flags such as accepted and ESPEI-ready record screening results, not certification; known issues are listed in the release notes.
