Abstract
Magnetic Iron oxides nanoparticles (NPs) were prepared by Laser Ablation in Solution method. Formation and average size of iron oxide NPs (~8 nm) is confirmed by XRD pattern and magnetization studies. Detailed magnetic studies have been carried out using SQUID magnetometer. The saturation magnetization for the iron oxide NPs was found to be 60.07 emu/g. Below the blocking temperature of 150 K the hysteresis loop shows ferromagnetic nature, whereas it shows superparamagnetic behavior at 300 K, for the synthesized NPs.
