Pulsed laser irradiation in liquids is a versatile and promising method for synthesis of colloidal submicrometer spheres are particularly attractive for bio-sensing, medical application, lithium-ion batteries (LIBs), catalysis, and photonics. Composite particles based on transition metal (Fe, Co, Ni) are successfully produced and tailoring by using laser method with various experimental parameters; wavelengths, laser fluence, irradiation time, raw material or solvent. The mechanisms involved in the formation of these particles are, however, still under consideration. Here, we focus our attention at the better understanding of the physical and chemical processes occupied in particles formation by pulsed laser irradiation in liquids. For this, a series of both experimental and numerical studies were performed. In particular, by using various experimental parameters composite particles with different size and composition were obtained. The structure, phase composition, size, morphology and magnetic properties were confirmed by XRD, TEM, EDS, SEM and SQUID.
