Abstract
We report magnetic and superlattice imaging of ferrimagnetic bilayered LuFe2 O4 with strong uniaxial magnetic anisotropy. Magnetization reversal is imaged in magnetic fields up to 8 T at several temperatures below TN (∼230 K) and charge-ordered superlattice domains are imaged at 92 K. We observed random packing of irregular pancakelike magnetic domains (∼100 nm×30 nm) and charge-ordered superlattice domains with similar shape (∼30 nm×6 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 LuFe2 O4.
