$R$V${_6}$Sn${_6}$ ($R$ = Y, Gd - Tm, Lu) single crystals are synthesized by Sn-flux method and their physical properties characterized magnetization, resistivity, specific heat measurements. Powder X-ray diffraction patterns of all samples can be well indexed with the hexagonal HfFe$_6$Ge$_6$-type structure, where rare-earth atoms form layers vanadium Kagome layers. At high temperatures, magne...

Mixed-valence phenomena associated with the highly correlated narrow-band behaviour of the 4f electrons in rare earths are well documented for a variety of rare-earth chalcogenides, borides and intermetallics (Kondo insulators and heavy fermions). The family of rare-earth fullerides with stoichiometry RE2.75C60 (RE=Sm, Yb, Eu) also displays an analogous phenomenology and a remarkable sensitivit...

Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state dilute 4f rare-earth impurities light metals. When subshells are open (but not half-filled), spin-orbit coupling imprints rotational charge current conduction electrons around atoms. The sign and amplitude oscillate similar to RKKY spin polarization. We compute observable e...
