We report magnetic and superlattice imaging of ferrimagnetic bilayered LuFe2O4 with strong uniaxial magnetic anisotropy. Magnetization reversal is imaged in magnetic fields up to 8 T at several temperatures below T-N (similar to 230 K) and charge-ordered superlattice domains are imaged at 92 K. We observed random packing of irregular pancakelike magnetic domains (similar to 100 nmx30 nm) and charge-ordered superlattice domains with similar shape (similar to 30 nmx6 nm). The magnetic domain structure shows a strong memory effect in magnetization reversal. Our results are consistent with a spin-charge cross-coupling mechanism in LuFe2O4.
