Magnetic CoPt Nanoparticles Deposition using Plasma Focus Device
A 3.3 kJ pulsed plasma focus device (NX2) was used to deposit magnetic CoPt nano-particles on Si (100) substrates at a low charging voltage of about 8kv. The hydrogen was used as filling gas at different gas pressures (2, 4, 6, and 8 mbar) to investigate the morphological, structural and magnetic properties of nanostructure thin films, using scanning electron microscopy (SEM), X-ray diffraction...
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 کاملNano- and micro-patterning biotemplated magnetic CoPt arrays.
Patterned thin-films of magnetic nanoparticles (MNPs) can be used to make: surfaces for manipulating and sorting cells, sensors, 2D spin-ices and high-density data storage devices. Conventional manufacture of patterned magnetic thin-films is not environmentally friendly because it uses high temperatures (hundreds of degrees Celsius) and high vacuum, which requires expensive specialised equipmen...
متن کاملSTEM nanodiffraction technique for structural analysis of CoPt nanoparticles.
Studying the structure of nanoparticles as a function of their size requires a correlation between the image and the diffraction pattern of single nanoparticles. Nanobeam diffraction technique is generally used but requires long and tedious TEM investigations, particularly when nanoparticles are randomly oriented on an amorphous substrate. We bring a new development to this structural study by ...
متن کاملThe Perpendicular Magnetic Anisotropy of CoPt/Au Multilayer Films
We have studied the magnetic properties of Au (2 nm)/Co50Pt50 (3 nm)/Au (2 nm) multilayer films prepared on amorphous Al2O3/Si and (0 0 1) MgO substrates. The as-deposited films on both substrates are magnetically soft with an FCC structure and exhibit a perpendicular anisotropy. After annealing at 500 °C, the sample on the Al2O3/Si substrate has become magnetically isotropic but the sample on ...
