Cerium Phase Transition
Research on modifying the transition pressure point of Cerium by dopping rare earth metals.
Investigated the effects of rare earth doping (e.g., Yb, La) on cerium, employing high-temperature and high-pressure synthesis to modulate phase transition pressures and explore the stabilization of high-pressure phases at ambient conditions.
Conducted synthesis experiments with various high-pressure assemblies under different power and pressure conditions; prepared bulk samples by removing impurities and polishing them inside a glovebox to minimize oxidation.
Performed X-ray diffraction (XRD) analysis to evaluate doping efficiency, sample purity, and oxidation state by comparing results with reference spectra for alpha-Ce and gamma-Ce phases; used GSAS software to refine lattice constants and validate structural changes.
Characterized phase transition behaviors and the electrical/magnetic properties of doped samples using diamond anvil cell (DAC) techniques under variable pressure conditions.
