Thermal effect limits in ultrahigh-density magnetic recording
In current longitudinal magnetic recording media, high areal density and low noise are achieved by statistical averaging over several hundred weakly coupled ferromagnetic grains...

Ultrafast magnetic field pulses as short as 2 picoseconds are able to reverse the magnetization in thin, in-plane, magnetized cobalt films. The field pulses are applied in the p...
Dynamic coercivity measurements in thin film recording media using a contact write/read tester
Thermally activated magnetization reversal processes become manifest in the dependence of the remanent coercivity on the time during which a magnetic field is applied opposite t...
Monodisperse FePt Nanoparticles and Ferromagnetic FePt Nanocrystal Superlattices
Synthesis of monodisperse iron-platinum (FePt) nanoparticles by reduction of platinum acetylacetonate and decomposition of iron pentacarbonyl in the presence of oleic acid and o...
Thermal stability of longitudinal magnetic recording media
Thermal processes may limit the lifetime of stored data and ultimately the achievable areal density in magnetic recording. To quantify this important problem, we have studied a ...
