Description

Fe-doped SrTiO3 nanoparticles were fabricated by sol-gel method using a solution that contained poly(vinyl pyrrolidone) (PVP), iron oxide (Fe2O3), strontium dinitrate (N2O6Sr), and titanium(diisoproproxide) bis(2, 4-pentanedionate) 75 wt% in 2-propanol. The precursor of SrTiO3 and Fe-doped SrTiO3 are acquired from sol-gel method. The SrTiO3 and Fe-doped SrTiO3 nanoparticles were successfully obtained from calcination of all precursors at 800 oC in argon for 2 h. The SrTiO3 and Fe-doped SrTiO3 nanoparticles were characterized by SEM, XRD, TEM and VSM. Room temperature magnetization results revealed ferromagnetic behavior for the Fe-doped SrTiO3 samples. The origin of ferromagnetism observed in the Fe-doped SrTiO3 nanofibers was also discussed.
Keywords : Strontium titanate, nanoparticles, ferromagnetic and diluted magnetic oxide.
