DESCRIPTION:Nanometric magnetic systems\, such as ferrites\, metallic oxide
 s\, and core@shell structures\, represent a group of promising materials d
 ue to their extensive technological potential and the possibility of advan
 cing our understanding of fundamental physics at the nanoscale. With this 
 in mind\, we synthesized core@shell nanoparticles CoFe2O4@NiO using an ada
 pted coprecipitation method and systematically investigated the structural
 \, morphological\, and magnetic properties of this nanostructured system. 
 We reported the achievement of core@shell nanostructures with pure phases 
 through structural and morphological characterization. Through comprehensi
 ve experimental magnetic analysis\, we evaluated the magnetic response of 
 the precursor phases and the core@shell nanostructure. We identified the 
 “wasp waist” behavior and the “exchange bias” effect\, indicating 
 exchange coupling between the phases at the interface. Ultimately\, our fi
 ndings allow us to consider the procedures employed\, including adapted co
 precipitation and calcination processes\, as a viable route for producing 
 high-quality core@shell nanostructures.\n\nRecife\, Pernambuco\, Brazil
