Abstract

We have made a new approach to design a novel magnetic material system on a basis of silicon and germanium nano-cluster crystals with polyhedral cage structure, where d- and f-block elements Mn and Ce are introduced endohedrally or exohedrally together with alkaline-earth metal Ba encapsulated inside the cage. In this system, the elements thus introduced act as the independent sources of magnetic- and conduction- electrons with having their strong correlations, giving rise to electron spin ordering in spite of the long-distant magnetic-atom position. Since these aspects can be realized with nano-scale control in clathrates, clathrates with magnetic elements will provide a new scientific stage for shedding a new light on magnetism.
