Magnetic domain observations of FePt and CoPt particles fabricated by IBICVD

Magnetic 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...

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

CoPt and FePt magnetic alloys grown on van der Waals WSe2(0001) surfaces and on arrays of SiO2 spherical particles

Multi-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...

Fabrication and nanostructure of oriented FePt particles

Thin films of oriented tetragonal FePt particles separated by amorphous alumina have been fabricated by electron beam evaporation. The ordering of the FePt particles without coarsening can be tailored by annealing conditions. The value of coercivity of the annealed film reached as high as 4.4 kOe. The perpendicular magnetic coercivity of the annealed film was slightly larger than in-plane coerc...
