abstract = "Alloys from the two solid solutions EuyFe4-xCoxSb12 and EuyFe4-xNixSb12 were synthesised by argon arc-melting and isotypism was established with the skutterudite-type structure LaFe4P12. The Eu-content of the samples was determined by Rietveld refinements and electron microprobe measurements EMPA confirming a gradual decrease of the maximum Eu-content from y = 0.83 in EuyFe4Sb12 to y = 0.44 in EuyCo4Sb12 and to y=0.56 in EuyFe2Ni2Sb12. Eu0.83Fe4Sb12 orders magnetically around 84 K and the transition temperature decreases as a function of the Fe/Co and Fe/Ni substitution. X-ray absorption edge and magnetic susceptibility measurements served to define the electronic configuration of Eu and the magnetic state of the polyanions [Fe4-xCoxSb12]. To evaluate the figure of merit, thermopower, thermal conductivity and electrical resistivity measurements were performed. Due to the Fe/Co-substitution the hole number is reduced and further compensated by the electropositive element. This influences the Seebeck coefficients significantly, which has a great impact on the figure of merit.",
