Abstract
SUMMARYIn this paper, we have investigated the growth technique of graphite‐coated nanomagnet particles to apply a sustainable environment technology by millisecond YAG pulsed laser ablation (PLA) method in ethanol solution using Fe bulk target. To control crystallized forms and/or grain size of nanomagnet materials, laser diode (LD) beam was irradiated to the ablation plumes, which were generated by this PLA method. In addition, magnetic field was applied to the ablation plumes, in order to separate a nanomagnet particle and a nonmagnet one. Ablation plumes were observed by high‐speed camera images, and they were reexcited by LD laser beam irradiation. In the case of magnetic field assist, ablation plumes were attracted to the magnet. This suggested that growth nanoparticles had magnetic property. Typical carbon‐coated nanoparticles, which grown by nonassisted PLA, were observed by TEM images, and these grain sizes were dependent on the pulsed width of PLA source. On the other hand, LD‐assisted samples showed there were rod‐sharped nanomaterials, and crystallization of these materials was β‐Fe3O4, γ‐Fe2O3 surmised by electron diffraction.
