Fe <sub>0.6</sub> Pd <sub>0.4</sub> Te <sub>2</sub> : A New Polymorph of FeTe <sub>2</sub> and PdTe <sub>2</sub> Stable at Ambient Pressure
Although the pyrite space group is a high-pressure polymorph of FeTe<sub>2</sub>, here we report Fe<sub>0.6</sub>Pd<sub>0.4</sub>Te<sub>2</sub> with the pyrite space group Pa-3 prepared using Pd substitution on the Fe atomic site with ambient pressure crystal growth methods. Fe<sub>0.6(1)</sub>Pd<sub>0.4(1)</sub>Te<sub>2</sub> single crystals show metal behavior above 15 K abided by the Bloch-Grüneisen relation and display resistivity upturn below 15 K due to disorder-related scattering of correlated electronic states.
