Abstract
Nanocrystalline particles of barium hexaferrite were synthesized by a sol‐gel combustion route using nitrate‐citrate gels prepared from metal nitrates and citric acid solutions with Fe/Ba molar ratio 12. The present paper aims to study the effect of addition of polyethylene glycol (PEG) solutions with different molecular weights (MW: 400, 2000, and 10.000 g/mol) on magnetostructural properties of barium hexaferrite. The formation of the barium hexaferrite was inspected using X‐ray diffraction (XRD) analysis, Fourier transform infrared (FT‐IR) analysis, thermogravimetric (TGA) analysis, scanning electron microscopy (SEM) analysis and vibrating sample magnetometer (VSM) analysis for magnetic measurements.

Summary
Nanostructured magnetic materials have been intensively studied, due to their applications in magnetic high-density recording media, sensors, and biomolecular separations. Prithviraj Swamy et al prepared barium ferrite nanoparticles using metal oxalate precursors mixed with PEG by self-propagating low-temperature combustion route They reported that, using polyethylene glycol (PEG) as a suitable economic fuel, good waterproof surfactant to form a shell. A sol-gel combustion technique using nitrate-citrate gels prepared from metal nitrates and citric acid solutions has been applied to synthesize barium hexaferrite nanopowder It is a low-cost technique suitable for the mass production, when compared to the other mentioned methods, and the formation temperature of barium hexaferrite and its crystallite size in presence of polyethylene glycol with different molecular weight were compared [13]. Effect of chain length of polyethylene glycol is investigated on formation of its physical structure and magnetic properties
