Core-shell morphologies of FePt and CoPt nanoparticles: An ab initio comparison
Large-scale first principles calculations for near-stoichiometric FePt and CoPt clusters with up to 923 atoms are presented including unconstrained structural relaxations. The energetic order and magnetic properties of 561 atom FePt and CoPt nanoparticles are evaluated with emphasis on segregated morphologies with Pt covered surfaces. The results imply that for CoPt particles segregation of Pt ...
متن کاملCore-shell of FePt@SiO2-Au magnetic nanoparticles for rapid SERS detection
In this study, multifunctional hybrid nanoparticles composed of iron platinum (FePt), silica (SiO2), and gold nanoparticles (AuNPs) had been developed for surface-enhanced Raman scattering (SERS) application. Core-shell structure of SiO2 and FePt nanoparticles (FePt@SiO2) was fabricated through sol-gel process and then immobilized gold nanoparticles onto the surface of FePt@SiO2, which displays...
متن کاملMulti-L1(0) domain CoPt and FePt nanoparticles revealed by electron microscopy.
The atomic structure of CoPt and FePt nanoparticles (with a diameter between 2 and 5 nm) has been studied by transmission electron microscopy. The particles have been produced by a laser vaporization cluster source and annealed under vacuum in order to promote chemical ordering. For both alloys, we observe a coexistence of crystalline and multiply twinned particles with decahedral or icosahedra...
متن کاملMagnetic Properties of Nanostructured CoPt and FePt Thin Films
Polycrystalline MgO underlayer films lead to different preferred orientations of 10 CoPt and FePt films after the annealing process, depending on the thickness of 10 films. 10 films with a thickness greater than 20 nm revealed mostly 10 [100] fiber texture and consequently in-plane anisotropy as determined by magnetic hysteresis. Strong perpendicular anisotropy due to the 10 [001] fiber texture...
متن کاملCore/Shell structured nanoparticles for imaging and therapy
Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...
