Barium hexaferrite nanoparticles with high magnetic properties by salt-assisted ultrasonic spray pyrolysis

•The first time to synthesize the hexagonal ferrites by ultrasonic spray pyrolysis.•Extremely short reaction time (20s) and relatively low reaction temp. (950°C).•Preventing agglomeration, and accelerating the nucleation and growth by NaCl.•High magnetic properties of the particles, compared to thos...
