Syzygium polyanthum extract-assisted biogenic synthesis of Co-doped Fe3O4 nanoparticles: structural, magnetic, and antimicrobial insights

Co-doped Fe3O4 nanoparticles from iron sand with Syzygium polyanthum extract were successfully synthesized. The nanoparticle phase was exclusively Co-doped Fe3O4 with a cubic spinel crystal structure, where the replacement of Fe3+ (ionic radius = 69 pm) by Co2+ (ionic radius = 74 pm) enhanced the la...
