Magnetic domain images

Figure 3. AFM (A and C) and MFM images (B and D) of a CoCrPt thin film medium directly patterned by FIB. Magnetic-domain images taken by spin-SEM after electron bombardment of a centered square for 1200 s (E) in-plane, and (F) out-of-plane magnetization component.

Fig. 7.1 Magnetic domain images were observed through the Kerr effect of Co-Ni-Fe-P soft magnetic underlayer on a disk substrate electroless-deposited (a) without and (b) with an external appUed magnetic field. The thickness of each sample is 1 pm [15]. 2004 IEEE...

Optically pumped GaAs tips or samples enable spin polarized vacuum tunneling to be observed [159, 160]. However, magnetic domain imaging has not unambiguously been demonstrated yet.

The second mode of operation is the non-contact mode, in which the distance between tip and sample is much larger, between 2 and 30 nm. In this case one describes the forces in terms of the macroscopic interaction between bodies. Magnetic force microscopy, in which the magnetic domain structure of a solid can be imaged, is an example of the non-contact mode operation.

The essence of the topographic methods is that they map the interrsity of the diffracted beam over the surface of the crystal. Defects affect the diffracted intensity, so give contrast in the image. The methods are quite sertsitive enough to reveal individual dislocatiorrs, precipitates, magnetic domains and other long-range strain fields but cannot reveal point defects except in dense clusters.
