Magnetic Characterization of web-like Carbon Nanotubes Catalyzed by Fe2O3 Via Pulsed Laser Ablation Deposition (PLAD) Technique

Web-like carbon nanotubes were synthesized via Laser Ablation Deposition (PLAD) in a T-shape stainless steel chamber. Nd-YAG laser with 532nm wavelength was used to irradiate the target of graphite and catalyst, with 5-7 ns pulsed width. Fe2O3 was used as catalyst to form the graphite target. The va...
