“…Additionally, the existence of La 5 Ni 19 was reported by Yamamoto et al 4) for the first time in 1997. They reported that this intermetallic compound exists only in a very narrow high temperature range not lower than 900 C. Figure 1 is a partial La-Ni phase diagram for Ni = 50-100%, constructed on the basis of these reports.…”
