“…Based upon this trend, by 2012, areal densities will exceed 1 TBit/in 2 . 2,3 As the magnetic volume (bit size) of current media materials continues to be reduced to achieve higher areal densities, the magnetization direction can randomly fl uctuate under thermal energy. This random fl uctuation is known as superparamagnetism and prevents longterm information storage stability.…”

“…Additionally, the magnetic easy axis of the FePt fi lm, which is along the [001] direction, should be normal to the substrate for high-density, perpendicular magnetic storage. 2,3,8 This paper primarily addresses the former topic of ordering while potentially controlling the grain coarsening by pulse-thermal-processing (PTP).…”

Rapid/Pulse Thermal Processing Research SummaryThe effect of pulsed-thermal-processing with high-density plasma arc heating is discussed for 20 nm thick nanocrystalline FePt thin fi lms. The dependence of the A1→L1 0 phase transformation on pulsed time and radiant energy of the pulse is quantifi ed through x-ray diffraction and alternating gradient magnetometry. For 100 ms and 250 ms pulse widths, the phase transformation was observed. Higher radiant energy densities resulted in a larger measured coercivity associated with the L1 0 phase.

Abstract-Processing of self-assembled magnetic nanocrystals has vitally scientific and technological interests. In this paper, three different kinds of self-assemblies of cobalt nanocrystals were processed using particles processed by thermal decomposition of cobalt carbonyl in toluene. In case 1, two-dimensional self-assembly of cobalt nanocrystals with an average particle size of 9.2 nm and polydispersity of 9% has been formed. In case 2, macroscopic whisker structures composed of self assembled cobalt nanocrystals (with an average size of 8 nm) were formed during the thermal decomposition under an externally applied magnetic field. The whiskers can be aligned in the longitudinal axis direction during drying using an external magnetic field. In case 3, one-dimensionally ordered, densely packed self-assemblies have also been prepared using cobalt nanocrystals with irregular shape and larger particle sizes (10 -20 nm). The formation of these different structures is attributed to the magnetic properties of cobalt particles with different sizes.
