Thermally assisted magnetic recording with bit-patterned media to achieve areal recording density beyond 5Tb/in2

Investigation of writing error in staggered heated-dot magnetic recording systems

“…The heating technique is handled via the Brillouin function, [22][23][24] which explains the relationship among K u , M s , and the heating temperature, T (K). Additionally, this paper assumes that the thermal profile is a Gaussian shape 25 according to…”

Mossbauer study of Thin Films based on FeM (M=Pt or Co)

“…In order to considerably increase the magnetic information recording density, it was proposed [1] to switch over from the longitudinal type of recording, to the perpendicular when the film magnetization is oriented perpendicular to the film plane. Further increase of recording density, i.e., transition to ultrahigh density perpendicular magnetic recording (PMR), requires, however, development of new materials (see [2,3] and references therein). Multilayer systems and Tb/Fe, Co/Pd, or Co/Fe based crystalline films are attracting broad interest [4][5][6][7][8] Figure 1 and looks as typical spectra of amorphous alloys and consist of a set of absorption lines, which result from differences associated with a transition of the Mössbauer isotope…”

Magnetization reversal and microstructure in polycrystalline Fe50Pd50 dot arrays by self-assembling of polystyrene nanospheres

“…hard disks and magnetoresistive random-access memory). [18,19] In such binary systems, the fraction of high anisotropy, ordered-L1 0 to disordered-A1 phase alloys strongly depends on film stoichiometry and thickness given the growth parameters (i.e. substrate, deposition temperature, deposition rate, and pressure).…”
