 Abstract: A high-pressure high-temperature synthesis involving initial reaction, nitrogen depletion and annealing yields a new E-type iron iridium nitride. Energy dispersive X-ray spectroscopy of metallographic samples evidence a main phase having a molar metal ratio of Fe:Ir = 2:1 within experimental error. Chemical analyses and thermogravimetric measurements quantify the nitrogen content to 1.07 wt% (x = 0.24) and 1.2 wt% (x = 0.27), respectively. Above 750 K, the phase Fe2IrN0.24 decomposes into solid solutions E-Fe(Ir) and -Fe(Ir) involving the release of N-2 at ambient pressure. Magnetic susceptibility data suggest long-range antiferromagnetic ordering at T-N = 27 K.
