Analysis of mechanical, thermodynamic, and thermoelectric properties of ferromagnetic SrFe4As12 skutterudite

SrFe4As12 shows a ferromagnet character with a magnetic moment of 1.76 μB at an optimized lattice parameter of 8.38 Å. The lattice thermal conductivity decreases with temperature due to rattling behavior of the filler atom. SrFe4As12 exhibits the high value of the figure of merit equal to 0.76 at 800 K.117
