Phase transitions in samarium at high pressures

The electrical behavior of Sm was studied for pressures up to 43 GPa and temperatures from 430 down to 2K. The two Neel temperatures at ambient pressure are found to move toward each other as the pressure increases and finally merge into one at the dhcp phase. At room temperature, it was found that Sm transforms to a new phase, presumably fcc, at approx 12 GPa. The phase line between the dhcp and the new phase appears to tie with the cusp of the bcc phase line. 9 ref.--AA
