Synthesis and Morphology of Face Centered Cubic (FCC) Fe-Pt Nanoparticles
نویسندگان: ثبت نشده
چکیده مقاله:
FePt nanoparticles with thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles are prepared by chemical synthesis and a salt-matrix annealing technique. Structural and magnetic characterizations confirm the phase transition from the disordered face-centered cubic structure. In this paper, 3 nm FePt nanoparticles are first synthesized by superhydride reduction of Fe and Pt. Transmission Electron Microscopy (TEM) images show that the hard magnetic FePt are agglomerated after annealing at 675°C. Scanning Electron Microscopy (SEM) images indicate that the size of FePt nanoparticles increase by increasing of the annealing temperature.

متن کاملRoom-temperature ferromagnetism in doped face-centered cubic fe nanoparticles.
The magnetism of Fe and its alloys has been at the center of scientific and technological interest for decades. Along with the ferromagnetic nature of body-centered cubic Fe, the magnetic properties of face-centered cubic (fcc) Fe have attracted much attention. It is well known that fcc Fe is thermodynamically unstable at ambient conditions and not ferromagnetic. Contrary to what is known, we r...

1 Abstract Protein Structure Prediction (PSP) is a grand challenge of bioinformatics with broad implications for com-binatoric optimization, computational geometry, and physical energy models. Under most accepted computational models, PSP is NP-hard, even when the chemical and physical properties of proteins are greatly simplified. The objective of PSP (also known as protein folding) is to sele...
