Effect of f-c hybridization on the γ→α phase transition of cerium studied by lanthanum doping
文献摘要：
The hybridization between the localized 4f level(f)with conduction(c)electrons in γ-Ce upon cooling has been pre-viously revealed in single crystalline thin films experimentally and theoretically,whereas its influence on the γ → α phase transition was not explicitly verified,due to the fact that the phase transition happened in the bulk-layer,leaving the surface in the γ phase.Here in our work,we circumvent this issue by investigating the effect of alloying addition of La on Ce,by means of crystal structure,electronic transport and angle resolved photoemission spectroscopy measurements,together with a phenomenological periodic Anderson model and a modified Anderson impurity model.Our current researches indicate that the weakening of f-c hybridization is the major factor in the suppression of γ → α phase transition by La doping.The consistency of our results with the effects of other rare earth and actinide alloying additions on the γ → α phase transition of Ce is also discussed.Our work demonstrates the importance of the interaction between f and c electrons in understanding the unconventional phase transition in Ce,which is intuitive for further researches on other rare earth and actinide metals and alloys with similar phase transition behaviors.
