Research Abstract

The duality nature of the f electrons, i.e. itinerant or localized, is an essential issue of the strongly correlated f electron systems.The purpose of the present project is to investigate the physical properties arising from the duality nature of the f electrons in rare‐earth compounds.We derive the Fermi surface for α-Ce by a relativistic linear augmented plane wave method within the framework of a local-density approximation. The Fermi surfaces thus obtained are composed of an hole sheet and an electron sheet, all of which have no open orbits. The Fermi surface topology is consistent with the experimental results for the high-field magnetoresistance.We have also studied the physical properties arising from the itinerant or localized nature of the f electrons in other transuranium compound like PuS, PuSe, PuTe, PuRu_2、PuRh_2、PuIr_2、PuPt_2、ThSn_3、Usn_3、NpSn_3、PuSn_3、PuRh_3、PuPd_3、PuPt_3.
