    We investigated the high-pressure structural transformations in gadolinium at room temperature. Up to a pressure of 106 GPa, gadolinium metal undergoes four structural transformations: h.c.p.→ Sm-type → d.h.c.p. → f.c.c. → t.h.c.p. The corresponding transformation pressures are: 1.5 ± 0.2 GPa, 6.5 ± 0.5 GPa; onset at 24.0 GPa and completion at 29.0 GPa; and between 44.0 and 55.0 GPa, respectively. We found a much larger stability range for f.c.c.-gadolinium phase than that reported by others.
