Figure 2 shows the angular dependence of H C and M R /M S in the as-deposited state (a, e), after the fi rst +400 kV/cm poling (b, f), after the subsequent − 400 kV/cm (c, g), and after the second +400 kV/cm poling (d, h)
Figure 3. Reciprocal space maps of a 200 nm thick BFO fi lm measured in di ff erent scattering planes using neutron di ff raction
Figure 3 shows reciprocal space maps of a 200 nm thick BFO fi lm revealed by neutron di ff raction where only one re fl ection is present, which indicates that the magnetic structure of BFO fi lm is G-type, rather than cycloids as seen in a previous study
Figure 4b shows the schematic of two initial polarizations ( − 1 − 11) and ( − 111) directions (blue arrows)
