The phase diagram of samarium has been studied by in situ synchrotron X-ray diffraction with a diamond anvil cell (DAC) up to temperatures of 800 K and up to pressures of 27 GPa. Equilibrium lines between the structures dhcp, fcc and distorted fcc were defined and a triple point was located at 11. 3 GPa and 345 K. A close examination of diffraction spectra has shown that the distorted fcc phase could not be represented by a rhombohedral crystal system inside its whole domain of stability. The experimental P-V-T data were fitted to a thermal-pressure model and the values for bulk modulus and thermal expansivity were obtained.
