Abstract: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
