研究了Sm在430~2K压力范围内的电学行为。发现在常压下，两个N‘eel温度随着压力的增加而相互移动，最后在dhcp相合并为一个温度。在室温下，我们发现Sm在大约12 Gpa的压力下转变成一个新的相，可能是面心立方。在dhcp和新相位之间的相线看起来与bcc相线的尖端相连。
The electrical behavior of Sm was studied for pressures up to 43 GPa and temperatures from 430 down to 2 K. The two N'eel 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, we found that Sm transforms to a new phase, presumably fcc, at about 12 GPa. The phase line between the dhcp and the new phase appears to tie with the cusp of the bcc phase line.
