Phase changes in f-electron metals: discrepancies between experiment and theory

PDF Version Also Available for Download.

Description

Using a diamond anvil cell, phase transformation and RT equation of state for lanthanide and actinides were studied to multimegabars. Experimental data are compared with theoretical crystal structural changes and P-V relations. A generalized trend for phase transformations in lanthanides can be seen, which has broad agreement with theory. Broad agreement is also seen for structural changes in lighter actinides, with some discrepancies. It is concluded that an accurate, robust theoretical base for predicting phase transformations in the f- electron metals can be developed by incorporating DAC data as markers for fine tuning the theory.
