WebApr 12, 2024 · We studied the relationship between the lattice constant and magnetism of L 1 0-ordered FePt under high pressure by means of first-principles calculations and synchrotron x-ray measurements.Based on our calculations, we found that the c/a ratio shows a local maximum at ∼20 GPa and that the Pt magnetic moment first remains … WebSonoelectrodeposition is a useful technique to make metallic nanoparticles, using ultrasound during electrodeposition to remove nanoparticles as they grow on the cathode surface. This paper reports some structural and magnetic properties of FePt nanoparticles prepared by this method. The as-prepared Fe45Pt55 nanoparticles were …
