A laser-based synthesis route for magnetic metallic glass nanoparticles

Phase control, especially for amorphous phase, is challenging with pulsed laser ablation in liquid (LAL), where ablated materials experience crystallization even at extreme cooling rate during particle solidification processes. Here, metallic glass nanoparticles (MG-NPs) were prepared by picosecond-laser ablation of a Fe78Si9B13 metallic glass (MG) in several organic solvents (i.e. ethanol, acetone, acetonitrile). The employment of ternary MG...
