Thermal plasma processed ferro-magnetically ordered face-centered cubic iron at room temperature

摘要: Here, we report tailor made phase of iron nanoparticles using homogeneous gas condensation process via thermal plasma route. It was observed that crystal lattice nano-crystalline changes as a function operating parameters the reactor. In present investigation have been synthesized in presence argon at pressures 125–1000 Torr and fixed input DC power 6 kW. possible to obtain pure fcc, bcc well mixed phases for powder form pressure. The product characterized understanding structural magnetic properties by X-ray diffraction, vibrating sample magnetometer, Mossbauer spectroscopy. data reveal fcc is ferromagnetically ordered with high spin state, which unusual whereas found be ferromagnetic usual. Finally, are co-related.
