✦ Synopsis

2 ;

(2) binary alloys containing multiple oxidation state actinides (particularly uranium) and nonactinide polyhedral clusters such as Be 13 centered icosahedra in UBe 13 and Pt 6/2 octahedra in UPt 3 . The f-block metals in heavy fermion superconductors not only exhibit multiple oxidation states but are also diluted enough by the other elements so that the separation between f-block metals in the structure is at least 4 A s . The f-block metals become part of the conducting skeletons of heavy fermion superconductors so that their conductivities arise at least partially through valence fluctuations involving f-electrons.
