Synthesis of nanoparticles using high-pressure sputtering for magnetic domain imaging
چکیده انگلیسی

We have developed a modified sputtering gun for direct synthesis of metallic nanoparticles, and used this system to produce magnetic domain images using high-resolution Bitter microscopy (HRBM). The nanoparticles are produced at 900 mTorr inside the gun and transported to the main vacuum chamber by the pressure difference between the chamber and the gun interior. Fe particles synthesized using the particle gun have been characterized using X-ray diffraction, atomic force microscopy, and transmission electron microscopy techniques. The particles are 15–30 nm in size with a pure BCC phase. Further, we have deposited these Fe nanoparticles on magnetic recording media and observed the domain patterns using optical microscopy, scanning electron microscopy, and atomic force microscopy. We achieve a spatial resolution of at most 80 nm.
