Improved Ammonolytic Synthesis, Structure Determination, Electronic Structure, and Magnetic Properties of the Solid Solution SnxFe4–xN (0 ≤ x ≤ 0.9)

19-Aug-2015 | Tanja Scholz; Richard Dronskowski, Inorganic Chemistry, 2015

We report a synthetic and theoretical study of the solid solution SnxFe4–xN (0 ≤ x ≤ 0.9). A previously published ammonolytic synthesis was successfully modified to achieve the metastable nitrides in phase-pure quality out of many competing phases. As TG-DSC measurements show, the thermal ...
