Crystal structure and physical properties ofEu0.83Fe4Sb12

${\mathrm{Eu}}_{0.83}{\mathrm{Fe}}_4{\mathrm{Sb}}_{12},$ was synthesized by arc melting in homogeneous practically single phase form. From Rietveld refinement isotypism was derived with the ${\mathrm{LaFe}}_4{\mathrm{P}}_{12}$-(skutterudite)-type, space group $\mathrm{Im}3¯,$ No. 204. The refinement also served to determine the Eu content of $x=0.83\mathrm{}\left(2\right).$ ${\mathrm{Eu}}_{0.83}{\mathrm{Fe}}_4{\mathrm{Sb}}_{12}$ orders magnetically below 84 K and isothermal magnetization measurements reveal a spontaneous magnetization reaching about $4.5{\mu }_{\mathrm{B}}/\mathrm{f}.\mathrm{u}.\mathrm{}$ at 6 T. The electronic configuration of the Eu ion in this compound appears to be close to the ${4f}^7$ state, thus behaving almost divalently. From the measurements of transport coefficients, the figure of merit Z was evaluated as $\mathrm{ZT}\approx 0.08$ at room temperature. The most outstanding property of this compound, however, is the significant magnetoresistance of about $130\%$ at $T=1\mathrm{}$ K for a magnetic field of 12 T but still $30\%$ near room temperature.
