From: Ferroelectric polarization and magnetic structure at domain walls in a multiferroic film
a, c HAADF-STEM images of the type II DW along the [100] and [\(\bar{1}10\)] direction, respectively. The dFeB-FeC is significantly decreased near the DW. b, d Corresponding simulated HAADF-STEM images. The DWs are indicated by red arrows. e Quantitative analysis of the dFeB-FeC values across the type II DW. The DW is denoted by the red dashed line. The black dotted lines indicate the dFeB-FeC in the bulk ε-Fe2O3. f Calculated dFeB-FeC and ferroelectric polarization near the DW. The ferroelectric polarization near the DW is reduced to almost zero.
