Pressure-Induced Structural Phase Transition in EuNi(2)P(2)

[Image: see text] EuNi(2)P(2) was studied with a diamond anvil cell (DAC) and X-ray diffraction (XRD). The structural evolution of powder crystal EuNi(2)P(2) under high pressure up to 137 GPa and its single-crystal structure up to 9 GPa were reported. The unique structural phase transition of this 1...

Sumario:[Image: see text] EuNi(2)P(2) was studied with a diamond anvil cell (DAC) and X-ray diffraction (XRD). The structural evolution of powder crystal EuNi(2)P(2) under high pressure up to 137 GPa and its single-crystal structure up to 9 GPa were reported. The unique structural phase transition of this 122-type crystal occurred above 70 GPa in powder crystal EuNi(2)P(2). The diffraction data from single-crystal EuNi(2)P(2) revealed the coordinate change of the P atom, and the stability of the crystal at 9 GPa was confirmed. The crystal EuNi(2)P(2) remained stable with a tetragonal phase without obvious symmetry changes during compression to 137 GPa.
