Magnetic properties of nanostructured CoSm/FeCo films

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...

Optical properties of nanostructured metal films.

Nanostructured metal films of platinum, gold and silver up to 675 nm thick we prepared by electrochemical deposition through templates of 700 nm diameter polystyrene spheres assembled as hexagonal close packed monolayer on an evaporated gold surface followed by removal of the template by dissolution in tetrahydrofuran. The reflection spectra of the films at normal incidence were recorded as a f...

Magnetic hardening in FePt nanostructured films

Nanostructured FePt films for magnetic media applications

Smaller, faster, denser and cheaper magnetic disk drives are demanded for information storage using magnetic media. Increase in high areal density in magnetic recording requires small bit cells with very small grain size. The reduction of bit cell volume and grain size will eventually be constrained by the undesirable thermal instability of magnetization due to the superparamagnetic effect, thu...
