Keywords: colloidal solution of nanoparticles, ferrite nanoparticles, magnetic nanoparticles, pulsed laser ablation
Nickel ferrite nanoparticles are synthesized by pulsed laser ablation of corresponding bulk target in the double distilled water. Focused output of fundamental and third harmonics from pulsed Nd:YAG laser operating at 40 and 25 mJ/pulse energy respectively was allowed to irradiate the target. Produced colloidal solution was red in color and stable for several days. UV-visible absorption, XRD, FTIR, VSM techniques are used for the characterization of synthesized Nanomaterials. Materials synthesized with 1064 nm laser ablation have high degree of magnetization a s compared to that synthesized by 355 nm laser ablation
