Rare earths filled Skutterudite are known for their improved thermoelectric properties and thus materials based on such structures are promising candidates for specific applications. Also, reduced grain size is considered a promising route to decrease the thermal conductivity of materials and therefore to improve the figure of merit of thermoelectric materials.

Here we present preliminary results concerning physical properties of RE-(Fe,Ni)4Sb12 nanostructurated skutterudite (RE = Y, Ce, Yb) obtained by spark plasma sintering of nanopowders.
