15. We see some evidence of laterally inhomogeneous reversal in magnetic force microscopy and static read/write tester images that show domains in a few unsaturated pillars.
16. Note that the FePt single layer 180 nm pillars in Fig. are not fully saturated, so the reduction factor compared to ECC-BPM structure could be even larger than 4.
17. The SFD is defined here to be the difference in field between when 10% and 90% of the pillars have reversed.

19. The high magnetic anisotropy of FePt requires small finite elements (1-2 nm), making the number of elements necessary to fill an 180 nm pillar over 2 000 000, which overburdens our current computational power.
