Comparison between magnetic properties of CoFe₂O₄ and CoFe₂O₄/polypyrrole nanoparticles

Anotacija

CoFe₂O₄/polypyrrole composite nanoparticles were synthesized using a high energy ball mill. Mössbauer and Fourier transform infrared spectroscopies, magnetization measurements and transmission electron microscopy were used for the characterization of samples. Specific loss power (SLP) was determined by exposing nanoparticles to an alternating magnetic field. Some changes in coercivity were observed and explained comparing CoFe₂O₄ nanoparticles with CoFe₂O₄/polypyrrole composite nanoparticles.
