Abstract

Angle-dispersive x-ray powder diffraction experiments were performed on samarium metal up to 50 GPa. We report that the high-pressure distorted-fcc phase has the same hR24 structure observed in praseodymium, but, unlike praseodymium, samarium does not undergo a transition to a second distorted-fcc phase. We also report a path-dependent transition to a new phase, the structure of which has not yet been determined, which occurs on annealing followed by pressure decrease.
