Property	Value	T (K)	Phases / composition	Class	Source	Location	Quote
Phase transition	620 K	620	magnetic	model	[4] Liu 2016	p. 13 report	For the BiNi phase, the temperature of the magnetic transition was fixed to be 620 K to fit the peak of heat capacities.
Phase transition	630 K	630	magnetic	experimental	[4] Liu 2016 cites Vassilev 2007 doi	p. 10 report	Although Vassilev et al.9 ascribed the detected magnetic transition temperature (630 K) to the presence of some unreacted Ni in the sample, Yoshida et al.16 and Samui et al.14 studied the magnetic transition of BiNi and confirmed the formation of pure compound BiNi in Ref. is the magnetic 14 through XRD analysis.

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.
