Magnetic dots

In Fig. 4(A) it can be seen that the AFM dot size is almost independent on the dwell time (e-beam irradiation time) while the magnetic dot diameter (MFM) increases almost linearly with the square root of the dwell time. 

The dependence of square root of dwell time per dot , means that the magnetic dots are produced by heat-conduction- induced phase change in the...

Let us consider the condition for thermal stability of the patterned-media with perpendicular anisotropy, based on a perpendicular M-H loop [28], The net M-H loop for a dot array is the statistic result of small Stoner-Wohlfarth model like square M-H loops of each magnetic dot. The thermally stable condition for a magnetic dot array is just that of the condition for a dot, which is the easiest to reverse among the whole dots. Using the beginning field of the reversal, namely, the nucleation field of the magnetic dot array, H, the condition is expressed as.

In magnetic printers, the basic idea is to form a latent image by means of a magnetic drum and a system of magnetic heads. Each magnetic head produces a row of tiny magnetic dots on the drum combined with the drum rotation, this step leads to the image to be printed. In the next step.
