Depositional remanent magnetization

Fig. 3 Hysteresis loops of Ni particles (full line), Ni ellipsoides (dotted line), and Ni wires (dashed line) deposited within the pores of porous silicon, whereas the morphology has been the same. The coercivity as well as the remanence decreases with increasing elongation of the metal nanostructures. The magnetic field has been applied perpendicular to the sample surface...

Figure 5. Surface and magnetic images for nanopillar arrays of 50 nm diameter and 100 nm pitch, (a) SEM image of the media surface, (b) MEM image for the as-deposited film in the demagnetized state (pillars are randomly magnetized but their magnetization is either upward (white) or downward (black)), and (c) MFM image at the remanent state after magnetic saturation (the white on the pillars indicates that they are saturated in one direction) [9].
