Microstructure evolution before and after the nitriding process. (a,b) FE-SEM images and (c) XRD profiles of the (a,c-i) as induction thermal plasma processed (as ITP) and (b,c-ii) nitrided FeNi NPs. (d) Magnetic hysteresis curves (room temperature) of the as ITP and nitrided FeNi NPs. Insets in the FE-ESEM images show the corresponding particle size distribution.
