摘要: Abstract Superparamagnetic iron oxide nanoparticles (SPION) Fe3O4 were prepared using different approaches: co-precipitation and sonochemical methods. This article is a comparative study on how synthesis techniques greatly affect the magnetic properties heating efficiency of such nanomaterial. Another important issue addressed here correlation between microstructure, colloidal stability, magnetization specific absorption rate (SAR) nanoparticles. The results reveal that method for polyethylene glycol (PEGylated) with size 5 nm leads to pseudo single domain smallest loop area. Additionally, large SAR values are obtained within 10–15 min low field.
