Ultrahigh-pressure phase transformations in the Ce(0.43)Th(0.57) alloy : Implications for f-electron behaviour under compression
Ultrahigh-pressure transformations in the Ce(0.43)Th(0.57) alloy were investigated up to 253 GPa in a diamond anvil cell utilising synchrotron X-ray diffraction. At the initiation of f-electron bonding, the fcc to bct transition was observed at 17 GPa. This pressure is close to the corresponding transition pressure in Ce metal (12 GPa) and is considerably lower than that in Th metal (60 GPa). The results presented suggest that there are strong nonlinearities in transition pressure as a function of alloying content for f-electron alloys.
