In this research, we produced Co0.6Fe2.4O4 nanoparticles covered by natural surfactants from Syzygium polyanthum extract. The results of XRD analysis showed that the Co0.6Fe2.4O4 nanoparticles were successfully synthesized, which was indicated by the presence of the spinel phase without other phases. The Co0.6Fe2.4O4 nanoparticles had a particle size of 12.1 nm. SEM image indicated that the morphology of the nanoparticles was spherical and agglomerated with an average particle size value of 34.2 nm. Furthermore, the FTIR spectrum showed the vibrational peaks of C=C and C-H at the wavenumbers of 1633 cm-1 and 2881 cm-1, indicating the presence of the surfactant Syzygium polyanthum. At the wavenumbers of 500-600 cm-1, the vibrational peaks of Fe-O and Co-O were overlapped, which indicated that the Co2+ ion has succeeded in replacing the position of the Fe3+ ion. Our data analysis results also captured that the Co0.6Fe2.4O4 nanoparticles using natural surfactants from Syzygium polyanthum are potential candidates as high-performance antifungal agents. © 2023 American Institute of Physics Inc..
